\

The given vertices of $\"\"$ are $\"\"$ .

\

Find the lengths of each side using distance formula.

\

The distance between two coordinate points are $\"\"$ and formula is $\"\"$ .

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

\

The measures of the sides are $\"\"$ , $\"\"$ and $\"\"$ .

\

Since the measures of three sides are not same, $\"\"$ is a scalene triangle.
