Which statement is true?

• X + Y = Z

• X + Y = W

• X + Y + Z = W

• X + Y = 180

Answer explanation

The external angle is equal to the sum of the opposite 2 angles. This is true because the sum of all 3 angles within a triangle is 180 and the sum of an interior angle and its adjacent exterior angle is also 180.
