Answer 1

Answer:A quadrilateral is a polygon in Euclidean plane geometry with four edges and four vertices. Other names for quadrilateral include quadrangle and tetragon. A quadrilateral with vertices A, B, C and D is sometimes denoted as {\displaystyle \square ABCD}

Step-by-step explanation:

Answer 2

Answer:

In geometry, a quadrilateral is a closed shape that is formed by joining four points among which any three points are non-collinear. A quadrilateral has 4 sides, 4 angles, and 4 vertices. 'Quadrilateral' is derived from a Latin word, in which, 'Quadra' means four and 'Latus' means sides. All 4 sides of a quadrilateral may or may not be equal.

Step-by-step explanation:

A quadrilateral is a polygon with four sides four angles and four vertices. Whenever we name a quadrilateral, we need to keep in mind the order of the vertices. For example, the following quadrilateral should be named as ABCD, BCDA, ADCB, or, DCBA. It cannot be named as ACBD or DBAC, since they change the order of vertices in which a quadrilateral is formed. The following quadrilateral ABCD has four sides: AB, BC, CD, DA and two diagonals: AC and BD.
