Question

If DEFG is a square, find m

Answer 1

b. 90°

Step-by-step explanation:

Recall: based on the properties of a square, a square has all its sides equal to each other. Also, all interior angles of a square are therefore right angle each. This means each internal angle of DEFG measures 90°.

Thus,

m<DEF is an internal angle. We can conclude that:

m<DEF = 90°
