δstu is an isosceles triangle.
δstu is an equilateral triangle.
δstu is a right triangle.

ΔSTU is a scalene triangle

Step-by-step explanation:

In order to find the type of triangle, we have to find the lengths of sides of the triangle.

The length can be calculated by using the distance formula:

So,

ST =

As we can see that the lengths of all sides are different, it can be concluded that the given triangle is a scalene triangle ..
