Pythagoras’ Theorem And Trigonometry
Gbogbo ọrọ náà
Pythagoras' theorem and trigonometry are not limited to flat triangles: they work in three dimensions too. The trick is to find the right right-angled triangle inside a solid, often by using a diagonal of a face as a stepping stone to the diagonal of the whole solid.
In this lesson (Extended tier) you will solve three-dimensional problems using Pythagoras' theorem and trigonometry, including finding the angle between a line and a plane.
