For example, a 3-sided polygon is a triangle, a 4-sided polygon is a quadrilateral, a 5-sided polygon is a pentagon, a 6-sided polygon is a hexagon, and so on. Polygon Chart. The following chart shows the naming convention of polygons on the basis of the number of sides that they have.
A polygon has three parts: Sides: A line segment that joins two vertices is known as a side. Vertices: The point at which two sides meet is known as a vertex. Angles: interior and exterior.
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up). Polygon comes from Greek. Poly- means "many" and -gon means "angle".
In geometry, a polygon can be defined as a flat or plane, two-dimensional closed shape bounded with straight sides. It does not have curved sides. The sides of a polygon are also called its edges. The points where two sides meet are the vertices (or corners) of a polygon. Here are a few examples of polygons.
The Rhombus. A rhombus is a four-sided shape where all sides have equal length (marked "s"). Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.
7.1: Regular Polygons. A regular polygon is a polygon in which all sides are equal and all angles are equal, Examples of a regular polygon are the equilateral triangle (3 sides), the square (4 sides), the regular pentagon (5 sides), and the regular hexagon (6 sides).
26 Μαΐ 2022 · A polygon is a closed plane figure with three or more straight sides called edges. An endpoint of an edge a vertex. A polygon is regular if all of its edges are the same length and all of its angles have the same measure. Polygons each have a special name based on the number of sides they have.
