:Angle sum property of triangle states that, sum of interior angles of a triangle is 180°.

prove
Start with the following triangle with arbitrary values for the angles:


Angle sum theorem
Since angle a, angle b, and angle c make a straight line,

angle a + angle b + angle c = 180 degrees

Since alternate interior angles are equal, angle a = angle x and angle b = angle y

Therefore, angle x + angle y + angle c = 180 degrees ...
