Question

Proof if the triangle is a right angled triangle or not

Answer 1

To proof if a triangle is a right angled triangle, Pythagoras theorems must be obeyed

Pythagoras theorem states that

`\begin{gathered} c^2=a^2+b^2\text{ where c = hypotenus, i.e the longest sides} \\ a,\text{ and b are the other two sides} \\ \end{gathered}`

nows, lets test the triangle with pythagoras theorem

longest side, c = 97, a = 65, b = 72
