This quiz/worksheet offers a quick and efficient way for you to determine how much you know about rhombuses. Rectangles have some properties that generic parallelograms do not. Video transcript. In mathematics education, the Van Hiele model is a theory that describes how students learn geometry.The theory originated in 1957 in the doctoral dissertations of Dina van Hiele-Geldof and Pierre van Hiele (wife and husband) at Utrecht University, in the Netherlands.The Soviets did research on the theory in the 1960s and integrated their findings into their curricula. Therefore, to prove it is a rhombus you must verify that all sides are the same length. 4. If a parallelogram has two consecutive sides congruent, it is a rhombus. In this video, I model how to write a geometric proof. Now that you understand what a rhombus is, let's explore some of the important properties and theorems related to it. <>>> �D-��\-��e[ԠVp��0�dkܿ�1�Э#�cV��Ĩ֯�%J��ͮ�٪璾"�/��j��8" We all know that a parallelogram is a convex polygon with 4 edges and 4 vertices. A square is a rhombus, but a rhombus isn't necessarily a square.
