∠A ≅ ∠D need to be congruent to show that ABC = DEF by ASA
What else would need to be congruent to show that ABC = DEF by ASA?
From the question, we have the following parameters that can be used in our computation:
The triangles
To show that triangle ABC is congruent to triangle DEF by the Angle-Side-Angle (ASA) postulate, we would need to prove that
- In addition to angle B being congruent to angle E
- And side AB being congruent to side DE
- Angle A is also congruent to angle D.
In other words, you would need to show that:
∠B ≅ ∠E
|AB| ≅ |DE|
∠A ≅ ∠D
Hence, the true statement is (c) ∠A ≅ ∠D
