Question

what is quadrilateral show a picture of it with definition​

Answer 1

Answer: In Euclidean plane geometry, a quadrilateral is a polygon with four edges (or sides) and four vertices or corners. Sometimes, the term quadrangle is used, by analogy with triangle, and sometimes tetragon for consistency with pentagon (5-sided), hexagon (6-sided) and so on.

Answer 2

Answer:

If A, B, C and D are four points in a plane such that (1) no three points are collinear (2) the segments AB, BC, CD, and DA do not intersect except at their end points;then the figure made up of four segments is called the quadrilateral with vertices A, B, C and D
