Answer: d. ∠u ≅ ∠v
Explanation:
We know that when two triangles are congruent then their corresponding parts are congruent.
This property is known as CPCTC.
Given: triangle stu is congruent to triangle vwx
Thus, all corresponding sides are congruent
a.segment st ≅ segment vw and d. segment su ≅ segment vx , both are correct.
All corresponding angles are congruent,thus
∠s ≅ ∠v
∠t ≅ ∠w
∠u ≅ ∠x
Thus, d is the option which is not true.
