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."
Continue ReadingA 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.

Full Answer >A heptagon is an equal-sided figure with seven sides. There are various ways to go about drawing this shape. One of the simplest and most accurate methods is by drawing three circles and two triangles. You need a compass, a ruler, a pencil, a protractor and a piece of paper.
Full Answer >A plane figure is two-dimensional, and a solid figure is three-dimensional. This difference between the two is what gives modern graphics for films and video games a more realistic look.
Full Answer >A convex quadrilateral is a four-sided figure with interior angles of less than 180 degrees each and both of its diagonals contained within the shape. A diagonal is a line drawn from one angle to an opposite angle, and the two diagonals intersect at one point.
