If you are given a triangle with a missing side or angle, there are four different methods that you can use to find the missing information (bold means… Continue reading Triangles in GCSE Maths

## A guide to trigonometry (SOHCAHTOA) – Part 1

Following on from the previous blog on Pythagoras’ theorem, this blog will be a guide to solving trigonometry questions. This guide will show you how to use trigonometry to find a missing side in a right-angled triangle. The next blog will build on this idea and show you how to… Continue reading A guide to trigonometry (SOHCAHTOA) – Part 1

## Easy as Py – a guide to Pythagoras’ Theorem

a2 + b2 = c2.That’s Pythagoras’ theorem. What it says is that in a right-angled triangle, the sum of the squares of the two smaller sides equal the square of the longest side (or hypotenuse).From my experience, most GCSE students understand what Pythagoras’ theorem is, but when it comes to… Continue reading Easy as Py – a guide to Pythagoras’ Theorem
