Students learn how to calculate a shorter side of a right-angled triangle using Pythagoras' Theorem.  As learning progresses they are challenged to apply Pythagoras' Theorem to more complex shapes.

Differentiated Learning Objectives
All students should be able to calculate either of the two short sides in a right-angled triangle using Pythagoras’ Theorem
Most students should be able to calculate the perpendicular height of an isosceles triangle when given its hypotenuse and base.
Some students should be able to calculate the area of an equilateral and isosceles triangle by calculating either its base or perpendicular height.
