Geometry Transformation Test Review

The video tutorial covers various geometric transformations, including rigid transformations, reflections, and rotations. It explains the differences between pre-images and images, and provides rules for performing transformations. The tutorial also demonstrates how to reflect shapes over axes and specific lines, and how to rotate shapes around the origin. Key concepts such as enlargement, transformation rules, and the effects of reflections on coordinates are discussed.

What is the main reason the transformation in question 5 is not considered a rigid transformation?

• The pre-image and image are different sizes.

• The pre-image and image are the same size.

• The pre-image and image are the same shape.

• The pre-image and image are both reflections.
