# Drawing shapes

This document is relevant only for the following hardware:

You should use the built-in user interface to do these challenges. Think about the points in each challenge and try to do it with as few blocks as possible.

## Challenge One: The Square

**Draw a square with sides 100mm long**

- Can you do it with as few programming blocks as possible?
- Did you use the “repeat” block?
- How many degrees is Mirobot turning in total?

## Challenge Two: The Octagon

**Draw an octagon with sides 70mm long**

- Did you build on what you did in step one?
- Did you use the “repeat” block?
- How many degrees is Mirobot turning in total?
- How did you work out the angle to turn?

## Challenge Three: The Triangle

**Draw an equilateral triangle with sides 100mm long**

- Did you build on what you did in the previous steps?
- How many degrees is Mirobot turning in total?
- How did you work out the angle to turn?
- Do you understand internal and external angles?

## Challenge Three: The House

**Draw a house shape with a roof**

- Did you use any of the shapes from the previous steps?
- Did you use the “repeat” block more than once?
- Did you think about internal and external angles?
