The sum of the measures of the angles in any triangle is 180 degrees.
this is the theorem.

This is the triangle sum Theorem.

Step-by-step explanation:

Given : The sum of the measures of the angles in any triangle is 180 degrees.

To find : This is the Theorem.

Solution: We have given that The sum of the measures of the angles in any triangle is 180 degrees.

By the triangle sum theorem :  Sum of all the interior angle of a triangle is 180 degree

Let a, b ,c are the angle of a triangle ,

Then a+b+c = 180 degree.

Therefore, This is the triangle sum Theorem.
