WebIf a transversal intersects two parallel lines, then each pair of corresponding angles are equal. Therefore, ∠1 = x. Also, ∠1 and (120° + x) form a linear pair, therefore, their sum must be supplementary. Therefore, ∠1 + (120° + x) = 180°. On substituting ∠1 = x in equation above, we get: x + 120° + x = 180°. 2x + 120° = 180°. robotime orreryWebAngle sum property of a triangle states that the sum of all three interior angles of a triangle is always equal to 180 degrees.
