Question

riangle RST has vertices R(–4, 4), S(–1, 2), and T(–3, 0). Triangle RST is rotated 360° clockwise using the origin as the center of rotation. Which graph shows the image of triangle RST after the rotation?
On a coordinate plane, triangle R prime S prime T prime has points (4, negative 4), (1, negative 2), (3, 0).
On a coordinate plane, triangle R prime S prime T prime has points (negative 4, 4), (negative 1, 2), (negative 3, 0).
On a coordinate plane, triangle R prime S prime T prime has points (0, 3), (2, 1), (4, 4).
On a coordinate plane, triangle R prime S prime T prime has points (negative 4, negative 4), (negative 2, negative 1), (0, negative 3).

Answer 1

A 360° rotation maps every point back to itself. So R' = (−4, 4), S' = (−1, 2), T' = (−3, 0) — the second graph.
