Question 1
Points: 1
Polygon EFGH has vertices E(-1, 3), F(1, 4), G(3, 3), and H(0, 0). Graph the figure and its image after a clockwise rotation of $90^{\circ}$ about vertex H. Then write the coordinates of polygon $E'F'G'H'$.
Explanation
A clockwise rotation of 90° about H(0,0) uses the rule (x, y) → (y, -x). Therefore E(-1, 3) → E'(3, 1), F(1, 4) → F'(4, -1), G(3, 3) → G'(3, -3), and H(0, 0) stays H'(0, 0).
