Question

Indicate the method you would use

Answer 1

SSS can be used to prove that the given triangles are congruent.

Explanation:

In the given two triangles ΔADC and ΔABC,

1. AD = AB = 7 units,
2. CD = BC = 8 units,
3. AC is common to both triangles,

Hence, ΔADC ≅ ΔABC by Side-Side-Side (SSS) congruence.

SSS congruence-

If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.
