ABCD are A(3,-2), B(3, 2), C(-3, 2), and
D(-3, -2).
a. Rectangle ABCD is rotated 90° about the
origin. What are the coordinates of the
vertices of rectangle A'B'C'D'?
b. What are the measures of the angles of
A'B'C'D'?

Answer: a) A'=(2, 3), B'=(-2,3), C'=(-2,-3) D'=(2,-3)

b) the measure of each angle is 90 degrees.

Step-by-step explanation:

a) To find the coordinates you need to know that (x,y) is changed to (-y,x). This means that they are flipped and changed from either negative to positive or positive to negative.

b) Each angle is 90 degrees because that shape is a rectangle with all equal right angles.
