We can define quadrilateral as a Polygon that has four sides. There are more properties associated to a quadrilateral as compared to a triangle. In a quadrilateral, one amazing aspect is that it can have parallel opposite sides. Hence, if every side holds a parallel opposite side, this shape is termed as a parallelogram.

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".

There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3 , 2 or no equal sides/angles: Equilateral Triangle

A quadrilateral can sometimes be called: a Quadrangle (" four angles "), so it sounds like "triangle" a Tetragon (" four polygon "), so it sounds like "pentagon", "hexagon", etc.

Properties, Types and Examples of Quadrilaterals. A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees.

May 13, 2024 · Triangles are classified into two groups: based on sides, 1) scalene, 2) isosceles, and 3) equilateral triangles; based on angles, 1) acute angle, 2) obtuse angle, and 3) right or right-angled triangles. The differences between the types are given below:

Jul 18, 2023 · In geometry, a quadrilateral is a two-dimensional closed shape or polygon that has four straight sides, four corners or vertices, and four interior angles. The sum of the interior angles is 360 degrees. The word “quadrilateral” comes from the Latin words quadri, meaning “four”, and latus, meaning “side.”
