Question

by applying SAS congruence rule you want to establish that triangle PQR is congruent to triangle FED it is given that PQ = FE and RP=DF. what additional information is needed to establish the congruence?

Answer 1

Angle Q =~ angle E  SAS means angle between two sides

Answer 2

in SAS congruence rule two side and one included angle(angle between two sides) are equal to two sides and one included angle of another triangle
hence angle P = angle F
