The postulate that can be used to prove that the given
Answer to Problem 17PPS
It is not possible to prove that the given triangles are congruent.
Explanation of Solution
Given:
The given figure is:
Calculation:
According to the SSS Congruence Postulate, if all the 3 sides of one triangle are congruent to the 3 sides of the second triangle, then the two triangles are congruent.
According to the SAS Congruence Postulate, if the 2 sides and the included
Looking at the given figure, one pair of sides is given to be congruent.
Due to the reflexive property of congruence, the second pair of sides are also congruent. But nothing can be said about the third pair of sides or the included angle.
Hence, it is not possible to prove that the given triangles are congruent.
