This video tutorial focuses on rigid transformations, including translations, rotations, and reflections. It explains how these transformations preserve measurements, such as corresponding points, sides, and angles. The video also covers the effects of 180-degree rotations on line segments and the properties of lines under rigid transformations. Finally, it concludes with a discussion on vertical angles and their measures.

What type of transformation does not alter the measurements of a figure?

• Rigid transformation

• Scaling

• Skewing

• Distortion
