Rotations can be described using x-y coordinates.

• True

• Flase

The horizontal axis of a coordinate grid is the:

• X axis

• Y axis

• Z axis

• Origin

The vertical axis of a coordinate grid is the :

• X axis

• Y axis

• Z axis

• Origin

The point where the X and Y axes cross is called the:

• X axis

• Y axis

• Z axis

• Origin

Rotations can be described using:

• Angles

• Shapes

• Vertices

• Faces

The most common angles used to describe rotations are

• Right and Obtuse

• Right and Acute

• 90, 180, and 270 degrees

• Straight angles
