Quadrilaterals are two-dimensional four-sided polygons on a plane. Quadrilaterals have the following properties: four sides, two diagonals, four internal angles (or vertices), the interior angles add up to 360°.Mon, 13 Apr 2026 12:35:00 GMThttps://www.k5learning.com/free-math-worksheets/third-grade-3/geometry/quadrilaterals-identifyStudents review different quadrilaterals such as squares, rectangles, trapezoids and rhombuses.

Since it is a polygon, you know that it is a two-dimensional figure made up of straight sides. A quadrilateral also has four angles formed by its four sides. AB, BC, CD and DA are the sides and A, B, C and D are the vertices of the quadrilaterals.Sun, 12 Apr 2026 16:32:00 GMThttps://www.khanacademy.org/math/cc-fifth-grade-math/properties-of-shapes/imp-quadrilaterals-2/v/quadrilateral-overviewA quadrilateral is defined as a two-dimensional shape with four sides, four vertices, and four angles. There are two main types: concave and convex. There are also various subcategories of convex quadrilaterals, such as trapezoids, parallelograms, rectangles, rhombi, and squares. Created by Sal Khan.
