Question

Identify or mark the missing side or angle that would make triangle ABC congruent to triangle PDF by AAS. ​

Answer 1

• Angle C and F

AAS (angle-angle-side) is the two angles and the non-included side congruence.

We are given one side and an adjacent angle. The missing part is the second angle, not including the marked side.

This is the angle C of ΔABC and angle F of ΔPDF.
