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
For a clockwise rotation of $90^{\circ}$ about the origin (vertex H), the rule is $(x, y) \rightarrow (y, -x)$. Applying this: $E(-1, 3) \rightarrow E'(3, 1)$, $F(1, 4) \rightarrow F'(4, -1)$, and $G(3, 3) \rightarrow G'(3, -3)$.
