Polygons Lesson What is a polygon A polygon is a simple, closed, two-dimensional figure formed by three or more line segments (sides). The following list of polygons, polyhedra and polytopes gives the names of various classes of polytopes and lists some specific examples. Learn about recognizing and naming different shapes, such as circles, ovals, triangles, and various types of quadrilaterals like rectangles, squares, rhombuses, and trapezoids. A quadrilateral is a polygon that has exactly four sides. Regular polygon formulas: sides, area, perimeter, angles. The maximal diameter (which corresponds to the long diagonal of the hexagon), D, is twice the maximal radius or circumradius, R, which equals the side length, t. ![]() A prism is a 3-dimensional solid structure whose parallel faces are polygon, and the other lateral faces are like rectangles. Learn 2d, 3d, and Geometry Shapes name in English. Including the circle, an ellipse is also a non-polygon shape. A polygon which has all the sides and angles as equal is called a regular polygon. Apart from the circle, all the shapes are considered as polygons, which have sides. It is also called a regular quadrilateral. The basic types of 2d shapes are a circle, triangle, square, rectangle, pentagon, quadrilateral, hexagon, octagon, etc. A polytope is a geometric object with flat sides, which exists in any general number of dimensions. Learn different types of shape names in English with Pictures. It has all four equal sides, and all are right angles that are equal.
