Question

The point about which a figure is rotated.

Answer 1

Answer:

The point about which the object is rotated can be inside the figure or anywhere outside it. The amount of rotation is called the angle of rotation and is measured in degrees. By convention a rotation counter-clockwise is a positive angle, and clockwise is considered a negative angle.

Step-by-step explanation:

Rotations About The Origin:

• 90 Degree Rotation. When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). ...
• 180 Degree Rotation. When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). ...
• 270 Degree Rotation.
