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°. Web32. There is always the "taxicab" proof. Start at a vertex and take a cab trip around the triangle. The cab will have turned through an angle of 360 o Extend the sides of the triangle appropriately and you will get three 180 o angles with the vertex angles being supplementary to the turns taken by the cab. flights canberra to brisbane direct https://wylieboatrentals.com
