Question

Parallelogram ABCD is rotated to create image A'B'C'D'.

On a coordinate plane, 2 parallelograms are shown
Which rule describes the transformation?

Answer 1

A Rotation

Explanation:

This transformation is an example of a rigid transformation, meaning that it remains congruent. The parallelogram was rotated at a certain point and that caused it to move to another quadrant of the graph. The rules of rotating a figure are:

When 90° clockwise-

(x,y) becomes (y,-x)

When 90° counterclockwise-

(x,y) becomes (-y,x)

When 180° clockwise or counterclockwise-

(x,y) becomes (-x,-y)

Note: If you get a problem saying 360° rotation that means the shape ends up in the same exact place as before. So think (x,y) stays (x,y)

I hope this answers your question!
