Exterior Angles:The exterior angles of a triangle are the angles formed on the outside of the triangle by each vertex. The vertex is the name given to the point or corner where two of the sides of the triangle meet. The plural for 'vertex' is 'vertices.'...
Convex polygons are shapes with straight edges and with interior angles that all measure less than 180 degrees. When it comes to finding the sum of the interior angles of a convex polygon, we can use the interior angle sum theorem formula. This theorem applies to all polygons, and ...
Thesum of an interior angle and the exterior angle on the same vertex is always 180° since they form a linear pair. What is the sum of all interior angles of a quadrilateral? The formula used to find the sum of the interior angles of a polygon is: S=(n-2) × 180°. In this ...
