XYZ is a triangle and Y A || XZ. Y 4 X Prove that the interior angles of a triangle sum to 180 degrees by moving statements into the correct boxes. Step 1: XYZ is a triangle and Y A || XZ because this is given information. Step 2: 22 2 24 and 23 2 Z5 because Step 3: m24 + mZ1+mZ5 = 180° because angles that complete a line sum to 180°. Step 4: m/2 +mZ1+mZ3 = 180° because when parallel lines are cut by a transversal, alternate interior angles are congruent when parallel lines are cut by a transversal, corresponding angles are congruent when parallel lines are cut by a transversal, alternate exterior angles are congruent of the addition property of equality of the subtraction property of equality of the substitution property of equality
