Answer to Problem 18PSC
Explanation of Solution
Given information:
Formula used:
The below properties are used:
Two triangles are congruent by SAS congruence rule.
If two sides of a triangle are congruent, the triangle is isosceles.
Proof:
It is given that,
As corresponding parts of congruent triangles are congruent, we get
As corresponding parts of congruent triangles are congruent, we get
By reflexive property, we get
By SAS congruence rule, we get
As corresponding parts of congruent triangles are congruent, we get
