This lesson will demonstrate how to use slope, midpoint, and distance formulas to determine from the coordinates of the vertices if a quadrilateral is a parallelogram in a coordinate plane. It is 1 of 6 in the series titled "Coordinate...

In this video segment from Cyberchase, Bianca injures her ankle while skateboarding and is confined to her bed. She has trouble reaching a few objects from her bed until her friend gives her a device made up of collapsible...

Learn how to find the areas and perimeters of triangles and special quadrilaterals.

In this lesson, students learn how the diagonals of a rhombus are related. They use interactive sketches to learn about the properties of the angles and diagonals of squares, rectangles, rhombuses, parallelograms, and other...

This interactive instructional activity investigates quadrilaterals and provides students with an opportunity to practice describing their attributes.

In this lesson, young scholars discuss what they know about shapes and their characteristics through a paper-folding activity that results in a parallelogram. Included are examples, discussion questions, and a reflection activity....

You can pick up some valuable pointers on how to find the area of a triangle, rectangle, and other quadrilaterals. When you finish working your way through the pages you can take an on-line "Test Bite," and check your understanding.

In this task, students ultimately use the definitions they are given for three types of quadrilaterals and what they know about parallel sides to identify that a square fits all the definitions and explain why. Aligns with 4.G.A.2.

Are you looking for a very basic website that will explain the basic properties of a quadrilateral? Use this site to learn about the properties of a square, rhombus, rectangle, parallelogram, trapezoid, and kite. There are also some...

[Free Registration/Login Required] This flipchart reviews segments, parallel and perpendicular lines and then introduces polygons including quadrilaterals. It has many real world examples of shapes and includes Activote assessment.

In this activity, students create geometric figures, and use analytic and coordinate geometry to investigate their attributes. They go through the process of proving that a quadrilateral is a parallelogram.

Interactive activities dealing with the areas of quadrilaterals figures.

Learn about the properties of 2-D shapes: circles, triangles, polygons, and quadrilaterals. Includes information, video, and examples about each, with games and quizzes for reinforcement.

For this task, young scholars are asked to draw a quadrilateral so that no two sides are congruent, no two angles are congruent, and no two sides are parallel. The task gives students the opportunity to prove that if we join the...
