Is triangle TVS scalene, isosceles, or equilateral? The vertices are T(1, 1), V(9, 2), and S(5, 8).

    Measure the distance between the points and you will be able to make this determination. Are you familiar with the distance formula?

    Not really.

    \[d = \sqrt{(x _{2} - x _{1})^{2} + (y _{2} - y _{1})^{2}}\]

    Oh, so I just plug in the numbers where they go?

    Yeah. Measure the distance from T to V. Then measure the distance from V to S. Finally, measure the distance from S to T. If you get three different distances, for example, you would say Scalene.

    Because each distance corresponds to the measure of one side of the triangle.
