A quadrilateral is a 4 sided polygon bounded by 4 finite line segments. The word ‘quadrilateral’ is composed of two Latin words, Quadri meaning ‘four ‘and latus meaning ‘side’. It is a two-dimensional figure having four sides (or edges) and four vertices. A circle is the locus of all points in a plane which are equidistant from a ...This video provides the student with a walkthrough on proving that a quadrilateral is a parallelogram.

Proving the quadrilateral’s diagonals bisect each other. Proving opposite angles are congruent. Proving consecutive angles are supplementary (adding to 180°) The quadrilateral proof technique was developed by the ancient Greeks, and was used by Archimedes in his work "The Method of Mechanical Theorems". Quadrilateral proofs are used in a variety of mathematical fields, including number theory, geometry, and calculus. Here is a paragraph proof: A rhombus is a quadrilateral with four congruent sides, therefore opposite sides of a rhombus are congruent. Parallelogram theorem #2 converse states that “if the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram”. Therefore, a rhombus is a parallelogram.Marriage is a significant milestone in one’s life, and marriage records play a crucial role not only in personal lives but also in various legal and administrative matters.
