If W(-10, 4), X(-3, -1), and Y(-5, 11) classify triangle WXY by its sides

As the lengths of the two sides is equal. i.e. WY =  WX . Therefore, the  triangle WXY is an isosceles triangle.

Step-by-step explanation:

Considering the triangle with the vertices

The distance between the W(-10, 4) and Y(-5, 11) is the length of the side WY.

So,

So, the length of the side WY .

Similarly,

The distance between the W(-10, 4) and X(-3, -1) is the length of the side WX.

So, the length of the side WX .

As the lengths of the two sides is equal. i.e. WY =  WX . Therefore, the  triangle WXY is an isosceles triangle.
