Question

If the sides of a triangle are 3cm,4cm and 6cm long, find wether triangle is a right angled triangle or not?

Answer 1

In a right angled triangle the hypotenuse is the greatest and its square equals to the sum of squares of the other two sides.

In this sum using the above explanation

6^2 = 4^2 +3^2

36 = 16+9

Since 16+9 = 25 and not 36

Therefore this is not a right angled triangle.
