What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape.

How do you identify a translation?

Back

A translation can be identified by the movement of a shape without any rotation or reflection.

What does it mean for a shape to be congruent?

Back

Two shapes are congruent if they have the same size and shape, meaning one can be transformed into the other through rotations, reflections, or translations.

What is the difference between pre-image and image?

Back

The pre-image is the original figure before a transformation, while the image is the resulting figure after the transformation.

What is the effect of a 90° clockwise rotation on a point (x, y)?

Back

The effect of a 90° clockwise rotation on a point (x, y) is to move it to the new position (y, -x).
