Front

What is the rule for a 90 degrees clockwise rotation about the origin?

Back

Front

What is the result of reflecting a point (x, y) over the x-axis?

Back

Front

What is the result of reflecting a point (x, y) over the y-axis?

Back

Front

What is the composition of transformations?

Back

A combination of two or more transformations applied to a figure.

Front

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

Back

It moves the figure without changing its shape or orientation.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips it over a line.
