Hypotenuse is the side with the greatest length in a right angled triangle. Hypotenuse is the side opposite to the right angle in a triangle. If a, b are the length of sides of the triangle the length of the hypotenuse is square root of a2 + b2. The online tool used to find the hypotenuse of a triangle is called as the Hypotenuse calculator.


Example 1: Find the length of the hypotenuse in the right angle triangle with sides of length 3 cm, 4 cm.
 
Given are the length of sides of a right angle triangle -  4 cm and 3 cm.
 
If the triangle ABC has angle C as the right angle
 
Then > side a = 4 cm; b = 3 cm and c is the hypotenuse.
 
c2 = a2 + b2
 
Therefore c = √(42+ 32) = √(16 + 9) = 5 cm.
 
Hypotenuse = 5 cm.



Example 2: Find the length of the hypotenuse in the right angle triangle with sides of length 12 cm, 5 cm.
 
Given are the length of sides of a right angle triangle > 12 cm and 5 cm.
 
If the triangle ABC has angle C as the right angle;
 
Then > side a = 12 cm; b = 5 cm and c is the hypotenuse.
 
c2 = a2 + b2
 
Therefore c = √( 52+ 122) = √(25 + 144) = 13 cm.
 
Hypotenuse = 13 cm
