Exploring Shape Properties Through Transformations

The video explores how different transformations affect angle measures and segment lengths. It discusses rigid transformations like translation, reflection, and rotation, which preserve both angles and lengths. However, non-rigid transformations like dilation and vertical stretch do not preserve these properties. Through examples, the video illustrates how sequences of transformations impact geometric properties.

What is preserved in a rigid transformation?

• Only segment lengths

• Neither segment lengths nor angle measures

• Only angle measures

• Both segment lengths and angle measures
