# Solutions 2.1: Introducing Turtle

Here are the solutions to the exercises from Lesson 2.1: Introducing Turtle.

### Exercise 1

Use Turtle and Python Shell to draw two squares of size 100. Draw them in such a way that they are next to each other 100 steps apart. Make sure that the drawing does not contain any other lines.

#### Solution

There are several ways how to do this. Since the squares are not touching, you must draw one square, lift the pen, move to a new location, put the pen down, and then draw the other square.

### Exercise 2

Use Turtle and Python shell to draw a triangle that has one side of length 100, the other side of length 120, and the angle between these 2 sides is  75 degrees.

#### Solution

In order to have an inner angle of 75°, the outer angle must be 180° – 75° = 105°.

And since we don’t know the length or angle of the third side, we must use the home() instruction to return to the starting point.

### Exercise 3

Draw a five-point star.

#### Solution

The hint to this exercise told us that the inner angle at each point is 180° / 5 = 36°. And since inner angle is 36°, the outer angle must be 180° – 36° = 144°.
