Learn all about the trigonometry of right triangles. A right triangle is a triangle that has 90 degrees as one of its angles.

If the sides of the right-angled triangle are labelled 𝑎, 𝑏 and 𝑐 then Pythagoras' theorem can be written as the formula 𝑎² + 𝑏² = 𝑐². Pythagoras' theorem can be used to find the length of line ...
