Question

Quadrilateral EFGH has vertices E(-1, 3), F(1, 4), G(3, 3), and H(0, 0). Graph the figure and its rotated image after a counterclockwise rot 180° about the origin. Then give the coordinates of the vertices of quadrilateral E'F'G'.

Answer 1

(x,y) become (-x,-y), so all you have to do is take those coordinates and make them negative unless they already are negative. For example: E (-1,3) would become E (1,-3) since two negatives cancel each other out. For the rest do this: F (1,4) becomes F (-1,-4). Do the same strategy for the rest of the points, then graph your answer.
