It also goes further to state that the measure of the exterior angle is equal to the sum of its two opposite interior angles. The formula for this theorem is pretty simple: For a triangle ABC, we have A+B+C = 180°. The triangle sum theorem has varied applications and can even be extended to problems involving other polygons. Mathamaniacs. A collection of three worksheets on the following topics:Sum of angles in a triangle: a worksheet on evaluating the third angle in a triangle given the other two using the fact that their sum is 180 degreesExterior Angles of a Triangle: a worksheet on the exterior angles of a triangle. The exercises require to use the fact that an. A triangle is a two-dimensional closed figure formed by three line segments and consists of the interior as well as exterior angles. As per the triangle sum theorem, the sum of all the angles (interior) of a triangle is 180 degrees, and the measure of the exterior angle of a triangle equals the sum of its two opposite interior angles.. Consider a triangle ABC as shown below: This 8-question worksheet provides students with practice applying the Triangle Sum Theorem and the Exterior Angle Theorem, through the use of algebra. I have options where you may choose to include the QR codes, or not. My students really enjoy using QR codes. They look at the activity as more of a game then a worksheet :)
