Check understanding
- Use correct notation for line segments (AB), angles (∠ABC), and parallel lines (AB ∥ CD)
- Sketch a regular hexagon and describe its rotational and reflective symmetry
- Identify and label perpendicular and parallel lines in a given figure using standard symbols
“If you ask your child to describe a triangle using proper geometry notation — naming its angles and sides with letters — can they do it clearly enough for someone else to draw it?”
