Question

Can you solve this question? (Geometry) Also, what type of condition is it? - SAS, AAS, ASA, SSS, HL

Answer 1

Given the triangles ACB and ECD :

They have the following:

1. AC = EC ( given )

2. BC = DC ( given )

3. m∠ ACB = m∠ECD ( the vertex angles are congruent )

So, the triangles are congruent by ( SAS ) [ side - angle - side ]

so, ≅
