This lesson explains the definition and properties of a quadrilateral. In Euclidean geometry, a quadrilateral is a four-sided 2D figure whose sum of internal angles is 360°. A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). xref
Square is a regular quadrilateral in which all four sides and angles are equal. The following types of quadrilateral are (1) Square (2) Rectangle (3) Parallelogram Identify the quadrilaterals that possess the property and check the appropriate box. The theory of a convex quadrilateral and a circle that forms Pascal points is a new topic in Euclidean geometry. 2This proof may be short, but the derivations of the two area formulas are a bit longer; see [17, pp.212–214] or [7] and [8]. Identify quadrilaterals. It is a special kind of parallelogram whose diagonals intersect each other at 90°.This is one of the special properties of rhombus which is very helpful in many mathematical calculations. 3) A quadrilateral is convex. of the intellectual properties of Engr. 0000006732 00000 n
