What does a 90-degree counterclockwise rotation about the origin involve?

Back

A 90-degree counterclockwise rotation about the origin involves moving each point of a shape to a new position that is 90 degrees counterclockwise around the origin (0,0).

How does a 180-degree rotation about the origin affect a figure?

Back

A 180-degree rotation about the origin flips the figure to the opposite side of the origin, effectively reversing its position.

What is a reflection in geometry?

Back

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

What is the effect of a rotation on the coordinates of a point?

Back

The effect of a rotation on the coordinates of a point depends on the angle of rotation and the center of rotation.

What is the difference between a rotation and a reflection?

Back

A rotation turns a figure around a point, while a reflection flips a figure over a line.

How can you determine the type of transformation from a graph?

Back

You can determine the type of transformation from a graph by analyzing the positions and orientations of the figures before and after the transformation.
