Lengths in Right-Angled Triangles


Students learn how to use Pythagoras' Theorem to calculate missing lengths in right-angled triangles.

As learning progresses, they solve more complex problems involving triangular shapes.

Differentiated Learning Objectives
  • All students should be able to use Pythagoras Theorem to find any length of a right-angled triangle.
  • Most students should be able to use Pythagoras Theorem to find the height or base of an isosceles triangle.
  • Some students should be able to prove Pythagoras Theorem using algebra.
