If W(-10, 4), X(-3, -1), and Y(-5, 11) classify ΔWXY by its sides. Show all work to justify your answer.

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.

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
