The Triangle Angle-Sum Theorem just states that the angles of any triangle must add up to be 180 degrees. For example, suppose you have triangle ABC and m<A=65 and m<B=36. Well, what is the measure of angle C? We can solve for <C by using the Triangle Angle-Sum Theorem. All we do is set up an equation like so: m<A + m<B + m<C = 180. Now just fill in the values we know, so the equation is now: 65 + 36 + x = 180. Now simply and solve for x and you get that x=79. Just to check you work, add up 65, 36, and 79 and you will get 180.

Give a example of theorem on geometry?
An example is Pythagoras's Theorem: that the sum of the squares of the two shorter side lengths of a triangle with a right-angle is equal to the square of the length of the side opposite the right angle.
