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 does it mean to reflect a shape across the x-axis?

Back

To reflect a shape across the x-axis, you flip it over the x-axis, changing the sign of the y-coordinates of its points.

What does it mean to reflect a shape across the y-axis?

Back

To reflect a shape across the y-axis, you flip it over the y-axis, changing the sign of the x-coordinates of its points.

Front

What is a rotation in geometry?

Back

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

Front

What is a 90° clockwise rotation?

Back

A 90° clockwise rotation turns a figure 90 degrees to the right around a center point.

Front

What is a 90° counterclockwise rotation?

Back

A 90° counterclockwise rotation turns a figure 90 degrees to the left around a center point.

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a figure from one position to another without changing its shape or orientation.

Front

What does it mean to slide a shape right 2 and down 3?

Back

It means to move the shape 2 units to the right and 3 units down on the coordinate plane.

Front

What is the definition of transformations in geometry?

Back

Transformations are operations that alter the position, size, or shape of a figure.

Front

What is congruence in geometry?

Back

Congruence means that two figures have the same shape and size, but may be in different positions.
