So theres 100 congruent triangles that each have a measure to 15°. How many of these triangles are needed to make a pinwheel

The Pinwheel is complete Circle which means it equals 360°

If you're given 100 triangles with angles 15° each,

Find how many triangles would make the pinwheel "P"

P = angle of a circle / angle of given triangle.

P = 360° / 15°

P = 24

So 24 triangles would be needed.
