The lengths of the three sides of a triangle are $\"\"$ and $\"\"$ inches.

Consider $\"\"$ , $\"\"$ and $\"\"$ .

The right angle triangle is depends on the pythogarean formula.

Hence $\"\"$ .

Check for solution.

$\"\"$ (Pythogarean formula)

$\"\"$ (Substitute $\"\"$ , $\"\"$ and $\"\"$ )

$\"\"$ (Evaluate powers: $\"\"$ and $\"\"$ )

$\"\"$ (Add: $\"\"$ )

$\"\"$ (Equation is not true)

Therefore,the values are not satisfied,then the triangle is not a rightangle triangle.

$\"\"$

The triangle is not a right triangle.
