Question

In ∆ABC, A = 30° , B = 40° and C = 110°

In ∆PQR, P = 30° , Q = 40° and R = 110°

A student says that ∆ABC ∆PQR by AAA Congruence criterion. Is it justified?

Answer 1

Answer:

Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles. When you're trying to determine if two triangles are congruent, there are 4 shortcuts that will work. Because there are 6 corresponding parts 3 angles and 3 sides, you don't need to know all of them.
