Question

how can you related angles and fractional parts of a circle

Answer 1

Lili,

 

       A Circle consists of 360 degrees. So if you have an angle that is created by two radii with a vertex at the midpoint that covers ,for example, 1/4 of the circle the angle would measure 1/4 of 360 degrees. You can do the math.

 

I hope this helps
