In a right triangle since one angle is always 90 the other two must always add up to 90. From Wikipedia the free encyclopedia For any interior point P the sum of the lengths s u t equals the height of the equilateral triangle. If c is the length of the longest side then a2 b2 c2 where a and b are the lengths of the other sides.
The interior angles of a triangle always add up to 180. The intersection of three lines. Sum of angles in a triangle - Triangle angle sum theorem.
The interior angles of a triangle are the three angles on the inside of a triangle. Because of this only one of the angles can be 90 or more. In this triangle below angles A B and C are all interior angles.
Look at the picture. Since triangles have three angles they have three interior angles. From the above diagram we can say that the triangle has three interior angles.

Label points on. 90 60 30 180 It works for this triangle. Angles A B and.
The angles denoted with the same Greek letters are congruent because they are alternate interior angles. The union of three line segments. S sum of interior angles S s u m o f i n t e r i o r a n g l e s.
As you can see from the picture below if you add up all of the angles in a triangle the sum must equal 180. As you are on the sphere and the radius is infinite then we can consider the curvature to be negligible and our triangle will seem to be a 2-dimensional triangle having the sum of interior angle equal to 270 degrees. The theorem states that interior angles of a triangle add to 180.
