Question

I need answer to this question.
Explain why triangle ABC is congruent to triangle FED.
​

Answer 1

Both triangles have right angles. Also the the two dashes on BC and DE indicate that those 2 sides of the triangles are the same. Angle A and angle F are also the same. This is what makes the triangles congruent

Answer 2

The two angles of ΔABC are equal to the two respective angles of ΔFED. Also, the sum of all interior angles of a triangle is 180º. Therefore, third angle of both triangles will also be equal in measure.
