Question

Which of the following statements must be true about the diagram? Check all that apply.

Answer 1

x + y = w

w > x

w > y

Explanation:

x and y are interior angles of a triangle.

w is the exterior angle ( opposite to angles x and y ) of a triangle.

There is a formula that exterior angle of a triangle is equal to sum of two interior angles of a triangle.

So,

x + y = w

If x + y = w,

Then,

w > x

w > y
