What is a reflection in geometry?

Back

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

Front

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

Back

The result is the point (x, -y).

Front

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

Back

The result is the point (-x, y).

Front

What is the result of reflecting a point (x, y) across the line y = x?

Back

The result is the point (y, x).

What is a rotation in geometry?

Back

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

Front

What is the result of rotating a point (x, y) 90° counterclockwise around the origin?

Back

The result is the point (-y, x).

Front

What is the result of rotating a point (x, y) 180° around the origin?

Back

The result is the point (-x, -y).

Front

What is the result of rotating a point (x, y) 270° counterclockwise around the origin?

Back

The result is the point (y, -x).

Front

What is a translation in geometry?

Back

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

Front

What is the translation rule for moving a point (x, y) to the left by 5 units and up by 2 units?

Back

The translation rule is (x, y) -> (x-5, y+2).
