Pythagoras Theorem
Share This Maths Concept
Pythagoras Theorem is a mathematical fundamental which tells a mathematical relationship between opposite side, adjacent side and hypotenuse of a right angle triangle. Pythagoras Theorem is also known as Pythagorean Theorem. This fundamental principle is mostly useful in trigonometry.
The square of a hypotenuse of a right angle triangle is equals to summation of squares of opposite and adjacent side of same right angle triangle is defined Pythagorean Theorem.
Consider a right angle triangle and its opposite side, adjacent side and hypotenuses are drawn as shown in the graphical image.

As per definition of Pythagoras Theorem, we can write it in mathematical form.
(Hypotenuse)2 = (Length of a opposite side)2 + (Length of adjacent side)2
It can also be written as stated below.
Hypotenuse = √[(Opposite Side)2 + (Adjacent Side)2]
