Pythagorean Theorem
: In a right angled triangle, the square of the length of the hypotenuse
is equal to the sum of the squares of the lengths of the remaining sides.
i.e. `AC^2 = AB^2 + BC^2`
Using Pythagoras
Theorem, Find out AC when AB = 5 and BC = 12
Here AB=5 and BC=12 (Given)
We know that,
In triangle ABC, by Pythagoras' theorem
`AC^2 = AB^2 + BC^2`
`AC^2 = 5^2 + 12^2`
`AC^2 = 25 + 144`
`AC^2 = 169`
`AC = 13`
