The triangle sum theorem is also called the triangle angle sum theorem or angle sum theorem.
Angle sum theorem math. Angles between adjacent sides of a triangle are referred to as interior angles in euclidean and other geometries exterior angles can be also defined and the euclidean triangle postulate can be formulated as the exterior angle theorem one can also consider the sum of all three exterior angles that equals to 360 in the euclidean case as for any convex polygon is less than 360 in the. The importance of this fact in geometry cannot be emphasized enough. X 24 32 180 sum of angles is 180 x 56 180. Proof of the angle sum theorem.
The triangle sum theorem states that the sum of the three interior angles in a triangle is always 180. Find the value of x in the following triangle. Exterior angle theorem and in the. Since alternate interior angles are equal angle a angle x and angle b angle y.
The triangle angle sum theorem is used in almost every missing angle problem in the.
