Is the triangle with sides and a right triangle? Give a reason for your answer.
Defining right angle triangle :
A right angle is a triangle in which one angle is a right angle or two sides are perpendicular. A right-angle triangle satisfies the Pythagoras theorem.
Let us consider,
applying the Pythagoras theorem,
Taking L.H.S.
Taking R.H.S.
Comparing L.H.S. and R.H.S.
L.H.S.R.H.S.
The sides do not satisfy the property of the Pythagoras theorem.
Hence, the given triangle is not a right-angle triangle.
