Coordinate grid Worksheet

1 a.

Draw a triangle with vertices (10, 8), (8, -7), and (3, 10). Then reflect it in the y-axis. What are the coordinates of the reflected shape?
1 b.

Draw a pentagon with vertices (-9, -3), (-2, -1), (9, -5), (9, -7), and (-6, -8). Then reflect it in the x-axis. What are the coordinates of the reflected shape?
2 a.

Draw a pentagon with vertices (-10, 8), (1, 7), (10, 8), (2, 5), and (-8, 4). Then reflect it in the x-axis. What are the coordinates of the reflected shape?
2 b.

Draw a triangle with vertices (5, 5), (1, 1), and (2, 9). Then reflect it in the y-axis. What are the coordinates of the reflected shape?
