Answer:
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.
