Question

What other congruence is needed to prove that △QRP≅△QFP by ASA?

QR≅QF
∠R≅∠F
∠QPR≅∠QPF
PR≅PF

Answer 1

The requirements for two triangles to be congruent by ASA are: a congruent side must be between two congruent and corresponding angles.

To prove that the two triangles are congruent by ASA, you need angles QPR and QPF to be congruent.

Answer = angle QPR congruent to angle QPF
