Transformations on Coordinate Plane

Front

What is a transformation in the coordinate plane?

Back

A transformation is an operation that moves or changes a shape in the coordinate plane.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

What is a translation?

Back

A translation moves a shape a certain distance in a specified direction without changing its size or orientation.

Front

What is a reflection?

Back

A reflection flips a shape over a line, creating a mirror image.

Front

What is a rotation?

Back

A rotation turns a shape around a fixed point at a certain angle.

Front

What is dilation?

Back

Dilation resizes a shape by a scale factor, either enlarging or reducing it.

Front

How does reflecting over the x-axis affect coordinates?

Back

Reflecting over the x-axis changes the sign of the y-coordinate.

Front

How does reflecting over the y-axis affect coordinates?

Back

Reflecting over the y-axis changes the sign of the x-coordinate.

Front

What happens to a point (x, y) when it is rotated 90 degrees counterclockwise?

Back

The point (x, y) becomes (-y, x) after a 90-degree counterclockwise rotation.

Front

What happens to a point (x, y) when it is rotated 180 degrees?

Back

The point (x, y) becomes (-x, -y) after a 180-degree rotation.
