Answer:
b. Congruent - SSS
Explanation:
Two triangles are congruent if their corresponding sides are equal and their corresponding angles are equal.
- If you are given three corresponding sides, then use SSS rule (each S stands for side);
- If you are given two corresponding sides and one corresponding angle, then use SAS rule (A stands for angle);
- If you are given one corresponding side and two corresponding angles, then use ASA rule.
In this case, three corresponding sides are given, then, SSS rule applies.
