Welcome to Quadrilaterals Explained (Intro, Properties, and Types) with Mr. J! Need help with quadrilaterals (quadrilaterals, trapezoids, parallelograms, rectangles, rhombuses, and squares)? You're in the right place!

Whether you're just starting out, or need a quick refresher, this is the video for you if you're looking for help with quadrilaterals. Mr. J will explain what quadrilaterals are, parallel sides of quadrilaterals, right angles in quadrilaterals, equal sides of quadrilaterals, and how to classify quadrilaterals.

⚠️ IMPORTANT ⚠️: This video follows the inclusive definition of a trapezoid. I understand that there are different opinions on trapezoids since there is not one standard definition across the board. So please keep in mind that this lesson uses the inclusive definition.
