It isn't a theorm, it is a formula. The formula states that for a polygon with S sides, the sum of the interior angles is equivilant to (S-2)times 180

Is the sum of the measures of the angles is 180 degrees?

In a triangle, the sum of the measures of the angles is 180 degrees.


If two angles of a triangle each measure 45 degrees what is the third angle?

If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.


All angles in a triangle equal 60 degrees?

If all angles in a triangle are equal to 60 degrees, then the triangle is an equilateral triangle. In an equilateral triangle, all three sides are equal in length. This property is a consequence of the triangle angle sum theorem, which states that the sum of the interior angles of a triangle is always 180 degrees. Therefore, if each angle is 60 degrees, the total sum of the angles in the triangle is 180 degrees, satisfying the theorem.
