Question

state the congruence relation for △abc and △def.
options: sas, sss, asa, aaa

Explanation:

Step1: Analyze triangle sides

In $\triangle ABC$ and $\triangle DEF$:

• $AB = DE = 4$ (given)
• $BC = EF = 4.5$ (given)
• $AC = DF = 3$ (given)

Step2: Identify congruence criterion

Since all three corresponding sides of the triangles are equal, the congruence criterion is SSS (Side - Side - Side).

Answer:

SSS (corresponding to the option with text "SSS")
