Unit 2 Review

Front

What are the coordinates of Point P' if Point P is at (4,5) and is rotated 90° counterclockwise?

Back

(-5, 4)

Front

What is the transformation shown if a figure is reflected over the line y = -1?

Back

Reflection over y = -1

Front

What are the coordinates of the point (-5,8) after rotating it 270 degrees counterclockwise around the origin?

Back

(8, 5)

Front

Which transformation will map a regular pentagon onto itself?

Back

216 degree rotation about the origin

Front

How many degrees was the figure rotated if it was turned 180 degrees?

Back

180 degrees

Front

What is a rotation in geometry?

Back

A rotation is a circular movement of a figure around a fixed point.

Front

What does it mean to reflect a shape over a line?

Back

To reflect a shape over a line means to create a mirror image of the shape across that line.

Front

What is the result of a 90-degree clockwise rotation of the point (1, 0)?

Back

(0, -1)

Front

What is the difference between rotation and reflection?

Back

Rotation turns a shape around a point, while reflection flips it over a line.

Front

What are the coordinates of the point (3, 4) after a 180-degree rotation around the origin?

Back

(-3, -4)
