WebBelow are some triangle properties worth noting. Angle sum. Using properties of parallel lines and alternate interior angles, we can show the sum of the interior angles for a triangle is 180°. For ABC shown above, let line DE, containing vertex C, be parallel to side AB. Since ∠DCE is a straight angle, ∠ECA + ∠DCB + ∠BCA = 180°.
