What is a Rotation in geometric transformations?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle.

What is a Reflection in geometric transformations?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

What is the effect of a translation on the shape of a figure?

Back

A translation does not change the shape or size of the figure; it only changes its position.

What is the effect of a reflection on the shape of a figure?

Back

A reflection creates a mirror image of the figure, preserving its shape and size.
