Mathematics Geometryusually ages 11–13

Types of angles (age 11+)

Use conventional geometric terms and notation to describe, sketch, and draw points, lines, parallel and perpendicular lines, right angles, regular polygons, and reflectively/rotationally symmetric polygons

How to tell they’ve got it

Tick these off as you see them — no test required.

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

Try this together

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?
