Define translation in geometry.

Back

Translation is a transformation that moves every point of a shape the same distance in the same direction.

What is rotation in geometry?

Back

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

Define reflection in geometry.

Back

Reflection is a transformation that flips a shape over a line, creating a mirror image.

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

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 a 180-degree rotation look like?

Back

A 180-degree rotation turns a shape halfway around a point, resulting in an image that is upside down.

What is the effect of reflecting a shape over the x-axis?

Back

Reflecting a shape over the x-axis flips it vertically, changing the sign of the y-coordinates.

What happens when a shape is reflected over the y-axis?

Back

Reflecting a shape over the y-axis flips it horizontally, changing the sign of the x-coordinates.
