Step-by-step explanation:
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), tetragon (in analogy to pentagon, 5-sided polygon, and hexagon, 6-sided polygon), and 4-gon (in analogy to k-gons for arbitrary values of k). A quadrilateral with vertices A,B,C and D is sometome denoted as ☐ ABCD.
The word "quadrilateral" is derived from the Latin words quadri, a variant of four, and latus, meaning "side".
The interior angles of a simple (and planar) quadrilateral ABCD add up to 360 degrees of arc, that is
∠A+∠B+∠C+∠D =180°
This is a special case of the n-gon interior angle sum formula: (n − 2) × 180°.
