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.
Learn MoreSome real-world examples of a trapezoid include a typical bicycle frame, the wings on an airplane, most tables, most desks and some purses. A trapezoid is a shape that has four sides, is flat and has a pair of parallel opposite sides.
Full Answer >The characteristics of a square are that it is a regular quadrilateral with equal sides and four 90-degree angles. Quadrilaterals can only be squares if they match a list of conditions, including that they must have two adjacent equal sides and be a rhombus with all equal angles.
Full Answer >A hexagon is a six-sided figure with six angles. Regular hexagons with equal sides and equal angles are a commonly found shape in nature. The honeycomb of bees, for example, is a naturally occurring instance of the hexagon. Minerals and crystals often form hexagonal shapes naturally, while the chemical compounds of graphene and benzene naturally form hexagons at the atomic level.
Full Answer >Find the diameter of a circle with a given circumference by solving for the formula "d=C/pi," where d is the diameter, C is the circumference and pi is 3.1459. For this problem, find the diameter of a circle that has a circumference of 18.8754 inches.
