About this printable
This printable shows twelve labelled angle relationships (e.g., adjacent, linear pair, vertically opposite, complementary, supplementary, corresponding, alternate interior/exterior, co-interior, co-exterior, angles at a point, perpendicular lines) each with a small diagram, a one-line description, and the algebraic statement (for example, a + b = 180°). It's designed as a classroom reference or display to support vocabulary and quick recall during lessons on angles and parallel lines. The clear icons and short formulas make it useful as a student reference during worked examples or practice.
