A five-sided shape is called a pentagon. In geometry, all two dimensional shapes are known as polygons, so it can also be referred to as a five-sided polygon.
Know MoreThere are two types of pentagon; regular and irregular. A regular pentagon has five sides of equal length.
An irregular pentagon has five sides of varying length. A regular pentagon will always have the same interior and exterior angles. The interior angle of a regular pentagon is 108 degrees and the exterior angle of a regular pentagon is 72 degrees. The total interior angles of a pentagon will always equal 540 degrees.

Full Answer >A trapezoid has four sides. It is a simple, convex quadrilateral with at least one pair of parallel sides. In British English, it is typically called a trapezium.
Full Answer >The formula for the surface area of a triangular prism is SA = bh + (s1 + s2 + s3)H. In this formula, "b" is the triangle base, "h" is the triangle height, "s1," "s2" and "s3" are the three triangle sides, and "H" is the length of the prism.
Full Answer >Geometric shapes found in nature include pentagons, hexagons, spirals, waves and lines. These shapes are fascinating examples of mathematical laws being manifested by natural or biological means.
