4. The coordinates of the vertices of rectangle
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′?

Sagot :

a. A'-- (2,3) B"-- (-2,3), C'-- (-2,-3), D'-- (2,-3) The formula for rotating a shape 90 degrees clockwise is (x,y) --> (-y,x).

b. 90 degrees because a rectangle has 90 degrees angles, and rotation doesn't change its shape, so it doesn't affect its angles.
