Quadrilaterals - Geometry

This geometry video tutorial provides a basic introduction into the different types of special quadrilaterals and the properties of quadrilaterals. It contains plenty of examples and practice problems of calculating the area, perimeter and diagonal length of many quadrilaterals such as squares, rectangles, rhombuses, kites, trapezoids, and parallelograms as well as missing sides and missing angles.

I just want to thank you, i had to drop out of school after life threw me a curveball and thus waking to having nobody at 15, im 40 now, been working steadily since. I decided to go and get my diploma, and with your help I'm understanding trig and calculus. I should graduate in june. And you have a big part in that in teaching me to understand it all. Thank you my man.

Who else is watching this just bcoz it's a test tomorrow

[jadepaige]

Thank you so much 😭
I was literally about to cry cuz I couldn't understand the way they explained it in the textbook and my maths teacher didn't really teach it to us, you are a life saver

MR. Organic Chemistry Tutor, thank you for another amazing video/lecture on the Introduction to different types of Special Quadrilaterals in Analytical Geometry. This is the beautiful and easy side of Geometry. All the different size and shapes are connected by Formulas and the Pythagorean Theorem.

Thank you so much mr. Organic. U rly rly rly helping me. I just wanted that I rly like ur work. ❤❤❤ this helped save my family from a fatal car crash. Luckily I saw that the corresponding angles were off so I swearved and didn’t kill my family. 🙏🙏
