A pentagon has vertices at (-1,-1), (-5,-2), (-6,-4), (-4,-7), and (-2,-3). If the pentagon is rotated 180* coordinates of the vertices of the image?​

Answer:

(1, 1) , (5, 2), (6, 4), (4, 7) and (2, 3)

Explanation:

When a point is rotated 180° about the origin(either clockwise or anticlockwise), the transformed coordinates are the negatives of the original coordinates.

Thus when a point (x, y) is rotated about the origin, its new coordinates become (-x, -y)

Given the original 5 vertices of the pentagon, the vertices of the rotated pentagon are transformed as follows

Original Vertex ==> Transformed Vertex

(-1, -1) ==> (1, 1)
(-5, -2) ==> (5, 2)
(-6, -4) ==> (6, 4)
(-4, -7) ==> (4, 7)
(-2, -3) ==> (2, 3)
