A closed figure made up of line segments is called a "polygon." The term "polygon" is derived from the Greek words "poly," which means "many," and "gon," which means "angle."
Know MoreA polygon is a two-dimensional geometric structure containing straight lines called "sides." One side of a polygon is connected to two other sides at their endpoints. If a polygon's sides and angles are equilateral and equiangular, respectively, then it is called a "regular polygon." Otherwise, the polygon is irregular. Other types of polygons include concave or convex and simple or complex. Some common polygons include triangles, pentagons, nonagons, quadrilaterals, octagons, decagons, pentagons, hexagons and heptagons.
Learn more about ShapesA geometric space figure is a three dimensional figure with points that do not share the same plane. Space geometry helps describe everyday objects such as buildings, tools and objects. These figures can have any number of faces, sides, vertices and edges.
Full Answer >A 12-sided polygon is called a dodecagon. A polygon is any closed figure with 3 or more sides and angles. Every polygon with 3 to 20 sides has a name. Polygons with 30, 40, 50, 60, 70, 80, 90, and 100 sides have specific names as well.
Full Answer >A three-sided figure can be called a polygon or more specifically, a triangle. All triangles are polygons, but not all polygons are triangles.
Full Answer >A square pyramid, a pyramid with four triangular sides and one square side, is a figure with five faces, eight edges and five vertices. It is a kind of three-dimensional solid. The pyramids at Giza, Egypt are examples of such a figure.
