## Reflections of Two-Dimensional Figures

1.
Point (2, 5) is the vertex of a triangle. When the triangle is reflected over the x-axis, what are the coordinates of the image of the vertex?
1. (5, -2)
2. (-5, 2)
3. (2, -5)
4. (-2, -5)
2.
Point (-3, 4) is the vertex of a triangle. When the triangle is reflected over the y-axis, what are the coordinates of the image of the vertex?
1. (-3, -4)
2. (3, 4)
3. (-4, -3)
4. (4, 3)
3.
Point (0, -7) is the vertex of a kite. When the kite is reflected over the x-axis, what are the coordinates of the image of the vertex?
1. (0, 7)
2. (7, 0)
3. (-7, 0)
4. (-7, 7)
4.
Point (-9, -1) is the vertex of a kite. When the kite is reflected over the y-axis, what are the coordinates of the image of the vertex?
1. (9, -1)
2. (-9, 1)
3. (1, -9)
4. (-1, 9)
5.
Graph the rectangle with the vertices listed on the grid.

A (-3, 3)
B (-1, 3)
C (-1, -5)
D (-3, -5)

Graph the image of rectangle ABCD reflected across the y-axis. Label its new vertices as:

$A -> A'$ $B -> B'$ $C -> C'$ $D -> D'$

What are the coordinates of the vertices of the reflected image?
1. A' (-3, -3), B' (-1, -3), C' (-1, 5), D' (-3, 5)
2. A' (-1, -3), B' (-3, -3), C' (-3, 5), D' (-1, 5)
3. A' (1, 3), B' (3, 3), C' (3, -5), D' (1, -5)
4. A' (3, 3), B' (1, 3), C' (1, -5), D' (3, -5)
