Given:
The vertices of ΔWXY are W(-10, 4), X(-3, -1), and Y(-5, 11).
To find:
Which type of triangle is ΔWXY by its sides. 
Solution:
Distance formula:

Using distance formula, we get





Similarly,


Now,

So, triangle is an isosceles triangles.
and,





So, triangle is right angled triangle.
Therefore, the ΔWXY is an isosceles right angle triangle.
