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.
