Answer: SSS
Explanation:
In the given figure we have two triangles having one common side and two pairs of equal corresponding sides i.e. 7 units and 8 units.
Therefore, by SSS postulate of congruence the given two triangles are congruent.
- SSS postulate of congruence says that if three sides of a triangle are congruent or equal to three sides of another triangle, then the triangles must be congruent.
