In a right triangle,
The sum of the 2 sides is>than the hypotenuse.
The sum of the squares of the first 2 sides of the triangle= to the square of the hypotenuse.
For eg.
In a triangle ABC,|_B =90*, AB=3cm,BC=4cm.
Find AC.
 AC^{2}= AB^{2}+ BC^{2} 
=> AC^{2}=4^2+3^2
=> AC^{2}= 16+9
=> AC^{2}=25
=>AC=sqrt{25}
=> AC=5 cm

In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
