Pythagoras’ theorem two ways
In this lesson, students use Pythagoras’ theorem to calculate unknown side lengths in right-angled triangles after undertaking a step-by-step method of working through visual and algebraic proofs simultaneously. This will help students to develop deeper connections between algebra and measurement in this context.
