Key stage 3 mathematics for using Pythagoras' Theorem to calculate any length of a right-angled triangle.   Learning progresses from working with Pythagorean Triples to calculating the area of a right-angled isosceles triangle when only the hypotenuse is given.

Differentiated Learning Objectives

• All students should be able to calculate a smaller side of a Pythagorean Triple
• Most students should be able to calculate any side of a right-angled triangle using Pythagoras’ Theorem
• Some students should be able to apply Pythagoras’ Theorem to composite triangular shapes.
