What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in a specified direction.

Front

What does the rule (x + 2, y - 1) represent?

Back

It represents a translation of a figure 2 units to the right and 1 unit down.

Front

What is a reflection in geometry?

Back

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

Front

What happens to the coordinates of a point (x, y) when it is reflected across the x-axis?

Back

The coordinates become (x, -y).

Front

What is a rotation in geometry?

Back

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

Front

What does a 90-degree counterclockwise rotation do to the point (x, y)?

Back

It transforms the point to (-y, x).

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

Front

If Point B (4, 3) is dilated by a scale factor of 3, what are the new coordinates?

Back

The new coordinates are (12, 9).

Front

What is the effect of a reflection across the y-axis on the point (x, y)?

Back

The coordinates become (-x, y).

Front

What does it mean to rotate a figure 180 degrees?

Back

It means to turn the figure around a point so that each point moves to a position directly opposite its original position.
