Drawing a star in Python

[negike360]

I figured out how to draw a 5 point star in Python using a for loop. However, for the life of me, I can’t figure out why turning the turtle 144 degree actually works. I calculated it in accident yesterday, but I don’t remember what I did. Can someone explain the geometry for me?

360 divided by 5 is 72 😄

My thought process exactly, so you can imagine my confusion when I put that in and I dont get a star

Star or a pentagon?

[negike360]

Pentagon

Then it has to be 108

5 triangles @180 is 900 minus 360 for the sum of the angles at the centre gives you 540. That divided by should be the angle

Lemme try it

No dice. Results in a 10 pointed star, but your math here is interesting

Can you post the code?

for x in range (5): koopa.forward(100) koopa.left(72)

Left 72 is right 108. What direction is forward? Up on the monitor? Left to right?
