Pythagoras
Watch this video to understand how Pythagoras Theorem can be used to calculate the length of any side in a right-angled triangle.
Pythagoras' Theorem states that in a right-angled The simplest two-dimensional shape is the triangle, a three-sided shape with three angles., the square of the The longest side of a right-angled triangle, which is opposite the right angle, is called the hypotenuse. is equal to the sum of the squares of the other two sides, ie \({a^2} = {b^2} + {c^2}\) (where \(a\) is the hypotenuse).
Look at the National 4 Pythagoras section before continuing.
