In Problems 15-17, draw the preimage and image of each polygon under the given rotation. 15. Polygon A(2,5), B(5, 4), C(5,2), D(1, 2); counterclockwise 180°
16. Polygon A(2,7), B(4,6), C(4, 3), D(-1, 5); counterclockwise 270°
17. Rectangle A(-1,5), B(5,5), C(5,3), D(-1, 3); clockwise 90°
18. Triangle ABC has vertices A(-2, 2), B(-7, 2), and C(-6,5). The triangle is rotated
270° about the origin. Will the coordinates of the vertices of the image of the triangle
have positive or negative x-coordinates? Explain your reasoning.
