Hints

There will be a few ways to do this. Below are hints for three different ways you can program this.

• Solution 1: By drawing a hexagon inside a star (see challenge 7.2).

• Solution 2: By drawing 6 triangles;

1. draw a triangle,
2. move back to the last vertex drawn,
3. turn 60 degrees (as if you are drawing a hexagon)
4. repeat steps 1-3 6 times).
• Solution 3: By drawing 2 triangles.
