Question

a right angled triangle whose sides are 3m 4m and 6m long determine whether the triangle is a right angled triangle

Answer 1

By Pythagoras theorem
${3}^{2} + {4}^{2} = {6}^{2}$
$= 9 + 16 = 36$
$25 = 36$
Since LHS is not equal to RHS , we can say that the given triangle is not right angled.
