Step-by-step explanation:
Given
Triangle PQR
Required
Which does not give a congruent triangle
The question has missing options. So, I will answer on a general term.
Any transformation that involve dilation will not result in a congruent triangle.
This is so because, dilation compresses or stretches the sides of a triangle, thereby changing the length of the triangle.
So, check the options and any of the options that has a dilation (stretch or compression) answers the question.
