| Topics |
Composition of parallel
line reflections -- examples on the coordinate plane.. Also classification
of quadrilaterals. |
| Class Schedule |
- Debriefing the lab - composition of line reflections
- Group: Detailed with composition of reflections in parallel lines.
- Handout: web page
or pdf file.
- Composition of two reflections in parallel lines is a translation.
- When are compositions of two pairs of line reflections equal to
the same translation.
- Solving for a mirror line given one line and a translation.
- Use algebra to see that any triple composition of reflections
in parallel line is equal to a single line reflection.
