Question

Which of the following transformations would make corresponding line

segments between a pre-image and image no parallel?

Reflecting over a line that is parallel to the line segment

Translating in a direction that is perpendicular to the line segment.

Rotating 180° about a point not colinear with the segment.

Rotating 90° around a point not on the line segment.

Answer 1

D

Explanation:

Consider the line y=x+1. Rotate this 90 degrees, and you get a line with a slope of -1, which obviously cannot be parallel.
