Question

In order to prove these two triangles are similar by AA you would need to:

Answer 1

To find:

What more information we need to prove two triangles are similar by AA similarity.

Solution:

From the figure, it is clear that angle C is congruent to angle F, because both are right angles that measure 90 degrees.

In AA similarity, two corresponding angles should be same to prove that both triangles are equal.

Here, if angle A could be shown congruent to angle D, or angle B colud be shown congruent to angle E. Both triangles can be proved using AA similarity.

Thus, option a is correct.
