What is a concave regular pentagon?
A pentagon is a geometrical shape, which has five sides and five angles. Here, “Penta” denotes five and “gon” denotes angle. The pentagon is one of the types of polygons. The sum of all the interior angles for a regular pentagon is 540 degrees. If a pentagon is regular, then all the sides are equal in length, and five angles are of equal measures. If the pentagon does not have equal side length and angle measure, then it is known as an irregular pentagon. If all the vertices of a pentagon are pointing outwards, it is known as a convex pentagon. If a pentagon has at least one vertex pointing inside, then the pentagon is known as a concave pentagon.
How to Calculate Area of Concave Regular Pentagon?
Area of Concave Regular Pentagon calculator uses area = ((Side^2)/4)*((sqrt(25+10*sqrt(5)))-(sqrt(10+2*sqrt(5)))) to calculate the Area, The Area of Concave Regular Pentagon formula is defined as measure of the total area that the surface of the object occupies of a concave regular pentagon, where a = concave regular pentagon edge, A = Area of concave regular pentagon. Area and is denoted by A symbol.
