Triangles: Interior and Exterior Angles Main Concept Aninterior angleof a polygon is formed by two sides of a polygon that share an endpoint. A shape has one internal angle pervertex. For atriangle, an interior angle is the angle between any two of the triangle's three sides. Anexterior a...
In a triangle,each exterior anglehastwo remote interior angles. The remote interior angles are just the two angles that are inside the triangle and opposite from the exterior angle. The Formula As the picture above shows, theformulafor remote and interior angles states that the measure of a an...
Exterior and Interior Angles of Triangles What are the Triangles? A triangle is a simple closed curve which is created by three line-segments. In geometry, any three points, specifically non-collinear, form a unique triangle and separately, a unique plane. The basic elements of the triangle ar...
It is known that the sum of the interior angles of a triangle is equal to 180°. This is a property of all triangles. It indicates that an exterior angle of a triangle is equal to the sum of the two interior angles that are not adjacent to it…...
