The correct formula for calculating the sum of the internal angles of a triangle is: Interior Angle Sum = (n - 2) * 180 degrees Where "n" is the number of sides (or vertices) of the polygon, and "n" is 3 for a triangle.
Sum of Interior Angles of a Polygon Main Concept An interior angle is an angle located inside a shape. For example, a triangle has three interior angles, with a sum of 180. As the number of sides, n , of a polygon increases, the sum of its interior angle
What is the sum of the measures of the interior angles of a pentagon? In other words, how many degrees are there in a pentagon? There is a formula to find the number of degrees in the interior angles of any polygon. Remember that the three interior angles of a triangle have a sum of...
One thing is for certain for all types of triangles: the measures of the three interior angles add up to 180 degrees. TheTriangle Angle Sum Theoremstates that the sum of all three interior angles of any triangle will always be 180 degrees. The use of this theorem is prevalent in the stud...
