Testing Congruence Through Transformations

The video tutorial demonstrates how to use transformations such as translations, rotations, and reflections to map a movable figure onto another figure named CORAL. The goal is to determine if the two figures are congruent by making one sit on top of the other. The process involves translating the figure to bring points in common, identifying reflections, and completing the transformation to confirm congruence.

What is the main objective of the task described in the video?

• To map the movable figure onto CORAL.

• To find the perimeter of the figure.

• To change the color of the figure.

• To measure the area of the figure.
