Geometric Reasoning and Trigonometry · Measurement and Geometry

Pythagoras Theorem

Utilising the relationship between the sides of right angled triangles to find missing lengths.

Key Questions

  1. 1How can we prove that the square on the hypotenuse is equal to the sum of the squares on the other two sides?
  2. 2Why is Pythagoras Theorem only applicable to right angled triangles?
  3. 3How do we determine if a triangle is right angled if we only know its side lengths?
