Pythagorean Theorem

This geometry video tutorial provides a basic introduction into the pythagorean theorem. It explains how to use it to find missing sides and solve for x. In addition, it provides examples of solving word problems using pythagorean theorem for shapes such as right triangles, squares, rhombuses, and trapezoids. This video explains how to calculate the perimeter of a rhombus and the area of a trapezoid using the pythagorean theorem as well as the side length of a square given the length of the diagonal. This geometry video contains plenty of examples and practice problems.

W Tutorial.

I love that it shows us multiple questions with the correct strategy to use! Its just so gooood!
Thank you!

MR. Organic Chemistry Tutor, thank you for another awesome video/lecture on the classical Pythagorean Theorem in Solid/Analytical Geometry. This topic is simple to understand from start to finish. All students in Mathematics should know and understand the Pythagorean Theorem.

c^2 = a^2 + b^2 is the converse of the Pythagoras theorem, where you use it to prove a triangle is a right angled triangle. The Pythagoras theorem itself is where if you know a triangle is a right angled triangle, you can use the property- a^2 + b^2 = c^2.

So thank you mate

[HelloSup]

How come when my teacher is the one teaching I don't understand a single word meanwhile this man explains in a speech and I get the whole lesson

[beenishhussain]

Mashallah brother have very good mathematics 😁

[venyon]

Thank you so much...! I got sick today and didn't focus on class so I had to study on my own T-T

With this, I now understand the lesson

Again, thank

[B.Revelation]

I feel like I am a pro now. Thanks for making life easy sir

[nicollynewton]

Thx for the challenging questions
Really woke up my 🧠

[dollqti]

I honestly hate hate hate anything to do with angles and geometry, im in 8th grade and i started learning abt the Pythagorean theory today, my teacher explained kinda quickly so I didn’t get it.. but u helped me so much so ty

[tochinzekwue]

Bro I watched this vid and more of your vids your a life saver bro because of you I gained admission into degenham church school
