Question

What is a $4$sided polygon?

Answer 1

Determining the $4$sided polygon.

Polygons are 2D geometrical figures with a fixed number of entities. The polygon's sides were formed of straight-line segments that are joined end-to-end. The polygon's segments are referenced as its sides or edges.

This place where two line segments meet is known as the vertex or corners, as well as an angle is generated as a result. The triangle with three sides is an instance of a polygon.

A polygon with four sides.

A quadrilateral is a four-sided polygon surrounded by four finite line segments. As a result, it's a 2D shape with $4$ sides and vertices.

Hence, A quadrilateral is a planar shape with $4$sides/edges and $4$corners/vertices.
