Question

The sides of a triangle are $4cm,60cm,61cm$. Verify that it is a right angle triangle or not.

Answer 1

Given sides $4,60,61$

$4^2=16$

${60}^2=3600$

${61}^2=3721$

$16+3600\ne 3721$

$3616\ne 3721$

Sum of square of two sides is not equal to the square $3rd$ side.

$\therefore$ by Pythagoras theorem It doesn't form a right angle triangle.
