Triangle Sum Theorem

Submitted by • September 14, 2012

According to triangle sum theorem sum of all the angles in a triangle is equals to 180 degrees. We can solve many mathematical problems using this sum theorem. Suppose we have a triangle ABC:
According to this theorem angles of triangle can be put into a relation as:
Angle (ABC) + Angle (BAC) + Angle (ACB) = 1800.
Proof for theorem can be given as follows:
