Concept explainers
To explain:
The parallel lines and collinear points preserved under all transformations.

Explanation of Solution
Given:
The parallel lines and collinear points preserved
Concept used:
Difference between parallel lines and collinear points.
Calculation:
All the points are moved the same distance horizontally and vertically.
The image is congruent to the preimage.
Corresponding
A figure is reflected in a line, all points are moved perpendicular to the line so that they are the same distance from the center of rotation and the angle of rotation is the same.
The image is congruent to the preimage.
The collinear point
