Every triangle in the figure at right is equilateral. what is the measure of ∠age?

step:

1. use the corollaries of the isosceles triangle theorem. each angle in an equilateral triangle measures 60° 2. use those two angles to find m∠age.

problem:
m angle agf =
m angle fge =
m angle age = m angle agf + m angle fge
= __ + __
=
