Answer to Problem 4CYU
The measure of the angle of rotation of ABCD about the origin is 180° .
Explanation of Solution
The vertices of the quadrilateral ABCD are A(0, 2), B(4, 8), C(8, 6) and D(4, 0) .
The vertices of the quadrilateral A′B′C′D′are A(0, −2), B(−4, −8), C(−8, −6) and D(−4, 0) .
The coordinates of the new quadrilatel is found by multiplying each coordinate of the vertices by −1 .
Thus, the quadrilateral is rotated by 180° .
Therefore, the correct option is (B) 180° .
