Resize and rotate different types of quadrilaterals--square, rectangle, rhombus, trapezoid, and kite--while learning the definitions of these different shapes and labeling the angles and diagonals. CCSS.Math.Content.3.G.A.1 Understand that shapes in different categories
In this lesson on 2D shapes, students will learn to discriminate quadrilaterals from other polygons. Additionally, they will be able to identify attributes of a square, rectangle, and rhombus.
Students connect algebra to geometric concepts with polygons as they explore the distance formula, slope criteria for parallel and perpendicular lines, and learn to calculate and justify the area and perimeter of polygons.
Quadrilaterals are figures with four sides and there are many different types. Watch this tutorial and try to figure out the name for any given quadrilateral. [11:03]
Video tutorial takes a look at parallelograms and explores what kinds of quadrilaterals can also be called parallelograms. [7:17]
Watch this tutorial to learn about quadrilaterals and their special types. [4:52]
This tutorial introduces you to the rhombus and explains its special properties. [5:15]
