the diagram shows parallel lines cut by two transversal lines creating a triangle. which statements are true? check all that apply.
∠a and ∠g are alternate interior angles.
∠a, ∠f, and ∠e form a straight line.
∠h and ∠a are corresponding angles.
∠e and ∠c are vertical angles.
m∠g = m∠e
m∠f = m∠c

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
