To explore the truth of this rule try math warehouses interactive triangle which allows you to drag around the different sides of a triangle and explore the relationship between the angles and sidesno matter how you position the three sides of the triangle the total degrees of all interior angles the three angles inside the triangle is always 1800. Then if you draw on extensions to the side lengths of each shape the exterior angles are the angles form between a side length and an extension. In the picture on the right the red angles are the interior angles of the triangle and the blue angles are the exterior angles. The interior or inside angles of a triangle always add up to 180 degrees.
1122009 61613 pm. The exterior angles of a triangle are the angles that form a linear pair with the interior angles by extending the sides of a triangle. Simply add the two non adjacent angles and you have found the measure of the exterior angle. 21 1 22 2 23 3 24 4 25 5 26 6 3 4 6 5 2 1 680 900 1220 x0 6x 70 103 x0 2x0 x0 560 x0 x0 x0 570 430 500 x0 530 620 800 650 x0 800 500 440 x0 title.
