How can I use the Pythagoras' Theorem to work out the length of a missing side of a triangle?
We have the triangle ABC. AB = 3 BC = 4 AC = ?
By inputting these numbers into the Pythagoras' Theorem, we can out the length of the missing side (AC).
a2 + b2 = c2
AB2 + BC2 = AC2
9 + 16 = AC2
25 = AC2
Square root both sides of the equation and we get AC = 5
