In brief

Master the SOH CAH TOA method to solve for missing sides or angles in right-angled triangles. This tutorial breaks down how to apply sine, cosine, and tangent ratios with clear examples, perfect for students or anyone brushing up on trigonometry basics.

Questions & answers

What do I need to know before starting this tutorial?

A basic understanding of right-angled triangles and their sides (opposite, adjacent, hypotenuse).

Can this method be used for non-right-angled triangles?

No, SOH CAH TOA only applies to right-angled triangles.

Description from the creator

SOH CAH TOA is used to remember the trigonometry ratios; sine = opposite over hypotenuse, cosine = adjacent over hypotenuse, tangent = opposite over adjacent. This helps you work out unknown side lengths or unknown angles in a right-angled triangle.
