4.2 Exploration, example 4
Directions
For examples #1-4, visually find the line of reflection and write its equation in the space provided. After, confirm your answer by doing the following:
- Use the line tool to construct the line of reflection on the graph
- Use the polygon tool to trace over the pre-image
- Use the reflection tool to reflect your polygon over the line
Example #4
Equation of the line of reflection
| A | (2,2) | B | (5,8) | C | (8,5) |
| A’ | B’ | C’ |
Write a coordinate rule for this transformation.
Write this rule in your notebook. You will need it for your homework and future assessments!
