The sum of 2 internal criss-crossing angles at the intersection of two parallel secant lines is 150 °. What are these angles equal to?
By theorem: The interior angles lying crosswise at the intersection of two parallel secant lines are equal. If the sum of two equal angles is equal to 150 degrees, then one of the angles accounts for half of the total sum of the angles, i.e. 150: 2 = 75 degrees.
Answer. 150 degrees.
