Reflections

2. What you will learn!
How to identify figures with line symmetry and graph reflections on a coordinate plane.

3. Vocabulary
Line Symmetry
Line of symmetry
Reflection

4. What you really need to know!

5. What you really need to know!
A type of transformation where a figure is flipped over a line of symmetry is a reflection.

6. What you really need to know!
To draw the reflection of a polygon, find the distance from each vertex of the polygon to the line of symmetry. Plot the new vertices the same distance from the line of symmetry but on the other side of the line. Then connect the new vertices to complete the reflected image.
