Important Formulaes of AREA 1. Pythagorean Theorem (Pythagoras’ theorem) In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides c 2 = a 2 + b 2 where c is the length of the hypotenuse and a and b are the lengths of the other two sides 2. Pi is a mathematical constant which is the ratio of a circle’s circumference to its diameter. It is denoted by π π ≈3.14≈22/7 3.
