Creating A Decagon On Turtle Academy: Step-By-Step Guide

Turtle Academy is a beginner-friendly way to learn Python by running some basic commands and viewing the turtle perform them graphically. To draw a decagon (a 10-sided polygon) on Turtle Academy, you can use the forward, backward, right, and left functions to move the turtle pen in the desired directions. The code will involve using a repeat loop to draw the 10 sides of the decagon, with each edge of a specified length. The turtle will need to turn a certain number of degrees after drawing each edge to ensure the decagon is symmetrical.

Using the forward, backward, left, and right functions

To create a decagon on Turtle Academy, you can use the forward, backward, left, and right functions in a repeat loop. Here's a step-by-step guide:

Initial Setup: Start by importing the necessary modules and creating a turtle object. You can name the turtle object as per your preference.

Python

From turtle import *

Turtle = Turtle()

• Understanding Decagons: A decagon is a polygon with ten sides. To draw a decagon, we need to repeat a sequence of forward and turn movements ten times, as each side of the decagon will be equal.
• Drawing the Decagon: Use the forward function to move the turtle pen forward and the right function to turn the turtle clockwise. The backward and left functions can also be used for movement and turns.

Python

Repeat 10 [fd 100 rt 36]

In this code snippet, `fd` represents the forward movement, `100` is the distance to move forward, `rt` represents the right turn, and `36` is the angle of rotation (360/10).

• Customizing the Decagon: You can customize the appearance of the decagon by adjusting the distance moved forward (`fd`) and the length of the sides. Play around with different values to create decagons of various sizes.
• Additional Functions: Turtle Academy provides other functions to enhance your drawing. For example, you can use cs to clear the screen at any point. You can also change the pen colour, thickness, and speed.

Here's a complete code example for creating a decagon:

Python

From turtle import *

Turtle = Turtle()

Repeat 10 [fd 100 rt 36]

Remember to adjust the values according to your desired outcome and explore the various functions available in Turtle Academy to create more complex and creative drawings.

Drawing polygons with different numbers of sides

To draw a triangle, you need to know that it has three edges, so the angle will be 360 / 3 = 120 degrees. You can use the following code:

Python

Repeat 3 [fd 100 rt 120]

Now, let's draw a square. A square has four sides, so the angle will be 360/4, and each edge is 100 units. Here's the code:

Python

Repeat 4 [fd 100 rt 90]

Moving on, we can draw a pentagon, which has five edges. The code will look like this:

Python

Repeat 5 [fd 100 rt 72]

Next up is the hexagon with six edges. The code for this polygon is:

Python

Repeat 6 [fd 100 rt 60]

Let's keep going and draw a heptagon, which has seven edges. The code for this polygon will be:

Python

Repeat 7 [fd 100 rt 52]

Finally, we'll draw an octagon with eight sides. The code for this polygon looks like this:

Python

Repeat 8 [fd 100 rt 45]

By adjusting the number of repetitions, forward movement, and rotation, you can create polygons with different numbers of sides using Turtle Academy.

Turtle Geometry

To create a decagon, we need to understand the relationship between the number of sides and the angles in a polygon. For any polygon, the sum of the angles is always 360 degrees. So, for a decagon, we divide 360 by 10 to get the measure of each angle: 360/10 = 36.

Now, let's use Turtle Academy to draw our decagon:

First, access the Turtle Academy website and open the coding environment. You can use the forward, backward, right, and left functions to move the turtle.

Python

Define the number of sides and the length of each side

N = 10

L = 100

Calculate the angle for each turn

Angle = 360 / n

Create the turtle pen

Turtle = Turtle()

Move the turtle to the starting position

Turtle.penup()

Turtle.backward(l)

Turtle.pendown()

Draw the decagon

For _ in range(n):

Turtle.forward(l)

Turtle.right(angle)

Return the turtle to the original position

Turtle.penup()

Turtle.goto(0, 0)

Turtle.pendown()

In this code, we first define the number of sides `n` and the length of each side `l`. Then, we calculate the angle for each turn by dividing 360 by the number of sides. We create the turtle pen and move it to the starting position by lifting the pen, moving backward, and then placing the pen down again.

Inside the for loop, we repeat the process of moving forward by the length of each side and then turning right by the calculated angle. Finally, we lift the pen, move the turtle back to the original position, and place the pen down again.

You can further customize your decagon by changing the color, thickness, or fill of the lines. Turtle Academy provides a variety of functions to manipulate these properties and create more complex and colorful designs.

Turtle Academy lessons

In this lesson, we will learn how to draw polygons using Turtle Academy. Polygons are closed shapes with three or more sides, and we can use Turtle to create some interesting geometric designs.

Basic Turtle Commands

Before we start drawing polygons, let's go over some basic Turtle commands:

• `forward(x)`: This command moves the turtle forward by x units in its current direction.
• `backward(x)`: Moves the turtle backward by x units.
• `right(n)`: Rotates the turtle clockwise by n degrees.
• `left(n)`: Rotates the turtle anticlockwise by n degrees.
• `setxy(x, y)`: Moves the turtle to the specified X and Y coordinates on the screen.
• `setheading(degrees)`: Rotates the turtle to face the specified heading.

Drawing a Triangle

To draw a triangle, we need to specify the length of each side and the angle between them. Let's say we want to draw a triangle with each side of length 100. We know that the sum of the angles in a triangle is 180 degrees, so each angle will be 180/3, or 60 degrees. Here's the code:

Repeat 3 [

Fd 100

Rt 60

]

This code uses a repeat loop to draw the triangle efficiently. We repeat the process three times (for each side of the triangle) – moving forward 100 units and then turning right by 60 degrees.

Drawing a Square

Now, let's draw a square. A square has four sides of equal length, and the angle between each side is 90 degrees. We'll use the same approach as before, but with different values:

Repeat 4 [

Fd 100

Rt 90

]

Drawing a Pentagon

A pentagon has five sides, so we'll repeat the process five times. Each internal angle of a regular pentagon is 108 degrees (360/5). Here's the code:

Repeat 5 [

Fd 100

Rt 108

]

Drawing a Hexagon

For a hexagon, we have six sides, and each internal angle is 60 degrees (360/6). Here's the code:

Repeat 6 [

Fd 100

Rt 60

]

Drawing a Decagon

Now, for the decagon. A decagon has ten sides, and each internal angle is 36 degrees (360/10). So, the code will look like this:

Repeat 10 [

Fd 100

Rt 36

]

In this lesson, we learned how to draw polygons using Turtle Academy. By using repeat loops and adjusting the number of sides and angles, we can create triangles, squares, pentagons, hexagons, and even decagons! Feel free to experiment with different side lengths and angles to create your own unique geometric designs.

Turtle motion queries

Turtle Academy is a beginner-friendly way to learn Python by running some basic commands and viewing the turtle perform them graphically. Turtle is an inbuilt module of Python that enables users to draw anything using a turtle and methods defined in the turtle module. Turtle drawings are drawn using four methods:

• Forward(x): moves the turtle (pen) in the forward direction by x units.
• Backward(x): moves the turtle (pen) in the backward direction by x units.
• Right(n): rotates the turtle (pen) by n degrees in a clockwise direction.
• Left(n): rotates the turtle (pen) by n degrees in an anticlockwise direction.

To draw a decagon, we need to use a repeat loop to make things more efficient. The decagon has ten edges, so the angle will be 360/10, which is 36. Inside the loop, the turtle will go forward and turn right.

Repeat 10 [fd 100 rt 36]

To draw a polygon, you need to know the number of sides (n) and the length of each side (l). You can then use the following code to draw any polygon:

N = int(input("Enter the number of sides of the polygon: "))

L = int(input("Enter the length of each side of the polygon: "))

Turtle.right(360 / n)

Turtle Academy also provides lessons on more advanced turtle motion queries, such as:

• Moving the turtle to the centre, pointing upwards.
• Moving the turtle to a specified X or Y location.
• Moving the turtle to a specified location.
• Rotating the turtle to a specified heading.
• Creating an arc with a certain distance and angle.
