Answer:
A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle) and tetragon (in analogy to, e.g., pentagon or hexagon)[citation needed]. A quadrilateral with vertices {\displaystyle A}A, {\displaystyle B}B, {\displaystyle C}C and {\displaystyle D}D is sometimes denoted as {\displaystyle \square ABCD}{\displaystyle \square ABCD}.[1][2]
The word "quadrilateral" is derived from the Latin words quadri, a variant of four, and latus, meaning "side".
Quadrilaterals are either simple (not self-intersecting), or complex (self-intersecting, or crossed). Simple quadrilaterals are either convex or concave.
The interior angles of a simple (and planar) quadrilateral ABCD add up to 360 degrees of arc, that is[2]
{\displaystyle \angle A+\angle B+\angle C+\angle D=360^{\circ }.}\angle A+\angle B+\angle C+\angle D=360^{\circ }.
This is a special case of the n-gon interior angle sum formula: (n − 2) × 180°.
All non-self-crossing quadrilaterals tile the plane, by repeated rotation around the midpoints of their edges
