What is a Polygon? In geometry, apolygon can be defined as a flat or plane, two-dimensionalclosed shapebounded with straight sides. It does not havecurvedsides.Thesidesof a polygon are also called its edges. The points where two sides meet are the vertices (or corners) of a polygon. ...

A line segment joining one corner to another but is not an edge is called a diagonal. In other words, a diagonal is a line that connects the opposite vertices of a polygon. Learn the definition, formula, examples & practice questions.
The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram. Which is a closed curve? A closed curve is a curve where the beginning and end points are the same. Is a hexagon a closed shape? A hexagon is a closed ...
A polygon is any 2D shape constructed from a finite number of straight lines. For example, a triangle is a three-sided polygon, and a square is a type of four-sided polygon, and so on. All of these polygons have angles both on the inside and the outside, but what do these angles...
In geometry, a trapezoid is a quadrilateral, or a two-dimensional shape with four straight sides, such that it contains one pair of opposite parallel sides. A trapezoid has four angles, and because it is a quadrilateral, we know that these angles satisfy certain properties....
