Quadrilaterals are polygons with four sides, however quadrilaterals with the same side and angle sizes are referred to as squares. From the center, the vertex will point outwards. Convex PolygonĪ polygon that is convex is a convex polygon is defined as one in which all of the internal angles are strictly less than 180 degrees. A scalene triangle, a rectangle, a kite, and so on. Irregular PolygonĪn irregular polygon is the one in which all of the sides and interior angles have distinct measurements. Squares, rhombuses, equilateral triangles, and other regular polygons are examples. Polygons are of numerous types based on their sides and angles, such as: Regular PolygonĪ regular polygon is one in which all of the sides and interior angles of the polygon are equal. It’s next to (to the side of) the internal angle. Exterior angles – Angles are created when a polygon’s side is extended outside the polygon.

Interior angles – Angles created at the vertices of a polygon’s vertices.There are two sorts of angles in a polygon: Although not all sources use the name “kai,” it was used by Kepler and supported by John H.Īlso, Read The CGPA Grading System and All You Need To Know About It Types of Polygon Angles The word ‘poly-‘ simply means ‘many,’ therefore a polygon is a form having numerous sides, similar to how ‘polygamy’ refers to several wives.įor the purpose of creating higher-level names, Combine the prefixes as follows to create the name of a polygon with more than 20 but less than 100 edges. Seven events make up an Olympic heptathlon, much as a heptagon has seven sides. The contemporary pentathlon consists of five events, similar to the five sides of a pentagon. Consider the following scenario:Īn octagon has eight sides, just like an octopus.Ī decagon has ten sides hence a decade is ten years. Some unique polygons have their own names, such as the regular star pentagon, which is also called the pentagram. Side counts that are easily articulated in verbal form (e.g., 20 and 30) or utilized by non-mathematicians are exceptions. Mathematicians frequently utilize number notation, such as 17-gon and 257-gon, in addition to decagons (10-sided) and dodecagons (12-sided). The exceptions are the triangle, quadrilateral, and nonagon. The number of sides, e.g., pentagon, dodecagon, by combining a Greek-derived numeral prefix with the suffix -gon. These can be helpful in remembering how many sides a polygon has on occasion. Many names of ordinary objects and concepts begin with the Greek number prefix. Polygons get their names from the prefixes of ancient Greek numerals. Before moving ahead know that the word polygon is comprised of two words meaning poly (many) and gon (sides). All polygons are two – dimensional figures, but not the vice versa is true. Often at times, one can consider all two dimensional figures as polygons but it’s not the case. Henceforth, that’s how an angle is achieved. Further, it’s this meeting point of line segments, which we address as a vertex or a corner. These edges are the sides of the figure which are connected from joint to joint or end to end. In geometry, we define polygon as a two – dimensional figure with a fixed number of edges. What is the best way to memorise polygon names?įirst things first, cutting the absolute non – essentials, let’s begin with talking about what a polygon is.
