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 more about ShapesA pentagon is the name for a five-sided polygon. However, there are different types of five-sided polygons, such as irregular, regular, concave and convex pentagons.
Full Answer >A polygon with seven sides is called a heptagon. A polygon is a closed geometric shape that has at least three sides and angles.
Full Answer >A four-sided polygon is called a quadrilateral. "Quad" means four and "lateral" means side, so quadrilateral truly means four sides. The internal angles in a quadrilateral add up to 360 degrees.
Full Answer >A four-sided shape is called a quadrilateral. All quadrilaterals have straight sides, are two-dimensional, have four vertices and have interior angles that add up to 360 degrees. Types of quadrilaterals include the square, rectangle, rhombus, parallelogram, trapezoid and kite.
