Answer 1

This is what I have
G: Triangles DEF and DEG; m<DEG = m<GFE = 60.
P: Triangle DEF is similar to Triangle DEG

1. m<DEG = m<DFE = 60 = Given
2. <DEG is congruent to <DFE = Definition of Congruent Angles
3. <D is congruent to <D = Reflexive Property of Congruence
4. Triangle DEF is similar to Triangle DEG = Angle-Angle Triangle Similarity Postulate
