In several geometries, a triangle has three vertices and three sides, where three angles of a triangle are formed at each vertex by a pair of adjacent sides. In a Euclidean space, the sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as 180 °, π radians, two right angles, or a half. A good example of the Triangular Sum Theorem would be when constructing a house. The roofs of houses are often formed as a triangle. To get the measurements, you must know the degrees of all three interior angles. Let's say that your two existing angles are 90 degrees and 45 degrees. Why is the sum of the angles in any triangle equal to 180 degrees? Find an answer to your question here along with a nifty proof of the angle sum theorem. basic Triangle Angle Sum Theorem.

Given theorem values calculate angles A, B, C, sides a, b, c, area K, perimeter P, semi-perimeter s, radius of inscribed circle r, and radius of circumscribed circle R. By investigating the angles of four different types of triangles, students conjecture about the interior angle sum of triangles and ultimately prove the triangle sum theorem.

Corollary If a triangle is equilateral, then it is equiangular. Using this corollary and the triangle sum theorem, it can be proven that the measure of each of the interior angles of an equilateral triangle is 60. Corollary If a triangle is equiangular, then it is equilateral. Corollary to the Triangle Sum Theorem The acute angles of a right triangle are complementary. m∠Am∠ B = 90⁰ EXAMPLE 1 Classify triangles by sides and by angles Shuffleboard Classify the triangular shape of the shuffleboard scoring are in the diagram by its sides and by measuring its angles.
