Angles and parallel lines

In this lesson, students will engage in various activities to explore angles between parallel lines in a navigational context. They will measure angles using traditional hand and finger techniques, construct parallel and perpendicular lines and establish laws of angle properties using algebraic formulas.

This lesson is based on activities from the Stellar navigation and mathematics resource from Ngarrngga. The project aims to empower all teachers to integrate Aboriginal and Torres Strait Islander histories and cultures in their teaching. Find more resources at https://www.ngarrngga.org/.
