Rigid Transformations and Reflections

Mr. Dell introduces rigid transformations, focusing on translating, rotating, and reflecting figures on a grid. He explains how to apply these transformations to move a figure from one part of the grid to another, using specific examples and steps. The video concludes with a summary of the transformation process.

In a translation, how is the movement of points described?

• By changing the x-coordinate

• By changing both x and y coordinates

• By keeping coordinates the same

• By changing the y-coordinate

How many units does the point move horizontally in the described translation?
