Quadrilateral - Wikipedia
In geometry, a quadrilateral is a four-sided polygon, having four edges (sides) and four corners (vertices). The word is derived from the Latin words quadri, a variant of four, and latus, meaning "side".

Quadrilaterals Quadrilateral just means "four sides" (quad means four, lateral means side). A quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.

Understanding Quadrilaterals: A Complete Guide
Any flat shape with four straight sides is a quadrilateral. The four vertices are typically labeled in order, such as A, B, C, and D. The sides are the line segments connecting the vertices, and the angles are formed at each vertex.

What is Quadrilateral ⭐ Definition, Properties, Types, Examples
What’s a Quadrilateral? The quadrilateral definition is quite simple. So, what is quadrilateral? It is a four-sided polygon, which means it is a geometric shape with four straight sides and four angles. It is derived from the Latin words “Quadri,” meaning “four,” and “latus,” meaning “side.”

Quadrilaterals - GeeksforGeeks
A Quadrilateral is a two-dimensional closed shape formed by four straight line segments. It has four sides, four vertices (corners), and four interior angles. The sum of all interior angles of a quadrilateral is always 360°. Quadrilaterals are either simplex (not self-intersecting), or complex (self-intersecting).

7.2.1: Quadrilaterals - Mathematics LibreTexts
Identify properties, including angle measurements, of quadrilaterals. Quadrilaterals are a special type of polygon. As with triangles and other polygons, quadrilaterals have special properties and can be classified by characteristics of their angles and sides.

Quadrilateral - Simple English Wikipedia, the free encyclopedia
Sometimes, a quadrilateral is called a quadrangle (similar to the term "triangle"), while other times, the term tetragon is used (similar to other polygon names such as pentagon and hexagon).
