Answer:
Option (d) is correct.
SSA is not a ways to prove triangles are congruent.
Step-by-step explanation:
Given : The ways to prove triangles are congruent.
We have to choose which one out of given options are not a ways to prove triangles are congruent.
Consider,
1) SSS - Two triangles are said to be congruent when all the three sides of the given triangles are same.
2) SAS - Two triangles are said to be congruent when two sides of a triangle are same and angle between them is equal.
3) ASA - Two triangles are said to be congruent when two angles of a triangle are equal and side is equal.
4) SSA - There is no such congruence conditions.
Hence, SSA is not a ways to prove triangles are congruent.
