Quadrilaterals - 3rd grade geometry lesson
In this lesson we look at some special quadrilaterals: rectangles, squares, and rhombi (rhombus). We locate those among a bunch of various quadrilaterals. Then, I show how to draw a rhombus inside a rectangle. Next, the task is to draw in a grid a rhombus and a quadrilateral that is not a rhombus and not a rectangle.
Lastly I show how to draw a neat pattern of rhombi using a ruler only. :) Try it at home too!
