WebThe interior angles of a triangle always add up to 180°. Because the interior angles always add to 180°, every angle must be less than 180°. The bisectors of the three interior angles … WebThe sum of the internal angle and the external angle on the same vertex is π radians (180°). The sum of all the internal angles of a simple polygon is π ( n −2) radians or 180 ( n –2) degrees, where n is the number of sides. The formula can be proved by using mathematical induction: starting with a triangle, for which the angle sum is ...
