Question

A triangle has sides with length of 8 millimeters 14 millimeters 15 millimeters is it a right triangle

Answer 1

$\begin{gathered} By\text{ pythagoras Theorem,} \\ \text{Hyp}^2=Opp^2+Adj^2 \end{gathered}$

If the Triangle satisfies Pythagoras Theorem then we conclude that it is a right angle triangle, otherwise, it is not a right angle triangle.

$\begin{gathered} 15^2=14^2+8^2 \\ 225=196+64 \\ 225=260 \\ So,\text{ it is clear that it is not right angle triangle.} \end{gathered}$
