Question

which congruence property could you use to prove these two triangles are congruent?
○ sss
○ sas
○ both sss and sas
○ neither sss or sas

Explanation:

Step1: Match corresponding sides

• 1-mark sides: congruent
• 2-mark sides: congruent
• 3-mark sides: congruent

This satisfies SSS (all 3 pairs of corresponding sides congruent).

Step2: Match included angles

The marked angles are the included angles between the 1-mark and 3-mark sides. These angles are congruent, so the pair of triangles also satisfies SAS (2 pairs of corresponding sides congruent, plus the included congruent angle).

Answer:

Both SSS and SAS
