1. Reflections and Graphs
13-7

2. I will sketch reflections on a coordinate grid.
line of reflection

4. Reflect Across a Horizontal Line
Graph the quadrilateral after a reflection across the line. Then write the ordered pairs for the new vertices.
Answer: The ordered pairs for the new vertices are (3, 7), (3, 9), (5, 9), and (7, 7).

5. Reflect Across a Horizontal Line
You can check the reasonableness of the vertices by drawing the quadrilaterals on grid paper. When the paper is folded, they should match exactly.
