Question

Determine if the following triangles are congruent

Answer 1

∆ABC ≅ ∆EFD by the SSS Congruence Theorem.

Explanation:

The digram shows that 3 sides of ∆ABC are congruent to the 3 sides of ∆ EFD.

Based on the Side-Side-Side Congruence Theorem (SSS), we can conclude that both triangles are congruent to each other.

Therefore:

∆ABC ≅ ∆EFD by the SSS Congruence Theorem.
