Question

'

Which missing piece of information would allow the triangles in the figure to be proven congruent by
ASA?

Answer 1

the measure of angle A' is equal to the measure of angle A

Explanation:

given :

m∠B = m∠B'

AB = A'B'

Since ,the side AB is between the angles ∠B and ∠A

and (if we want to prove the congruence by ASA)

Then

the missing piece of information is :

m∠A = m∠A'
