Students are guided through the discovery of Pythagoras’ Theorem and learn how to apply it to calculate an unknown side in a right-angled triangle. As learning progresses they are challenged to solve a range of problems using Pythagoras’ Theorem.
Geometry and measures
How to introduce the sin, cos and tan trigonometric identities.
How to teach calculating the original amount after a percentage change.
The importance of the range when comparing comparing datasets.
