Given two sides of a triangle determine the missing length

Learn about the Pythagorean theorem. The Pythagoras theorem is a fundamental relation among the three sides of a right triangle. It is used to determine the missing length of a right triangle. The Pythagoras theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Pythagoras theorem can also be used to determine if a triangle is a right triangle or not. The pythagoras ineaquality can be used to determine if a triangle is an acute, right, or obtuse angle. This can be helpful if you are just given the lengths of each side of a triangle rather than trying to graph the triangle.

praise Brian for being the first person on Youtube to help me with math

[oliverrooke]

in the beginning “ u look really sad”😂

[Leo-ckpz]

My man Brian clutching it up for us rn. I respect you Brian

[seattlewest]

“U look really sad” why you gotta call me out like that bruh

[ChrisHavok]

Thanks, Brian.
I've learned so much more from you in a 5-minute video than a 2-hour lecture from my professor.
Never stop doing what you do.

[raquelspaulding]

good explanation. talking about the right angle (90 degrees) and the hypotenuse, really helps with beginners. Thank you!

[foolishwynter]

wow you actually explain the problems you are better then 98% of my math teachers

[ninoangelojoson]

Thanks mister! I had this lesson in my class and I had to find an alternative because I forgot how to to do so thank you mister Brian!

[adriangomez]

you need a raise because you don't just teach your class but you also teach hundreds of thousands of kids with their math

[rltthatsme]

Brian, saviour of homework and tests.

[Thegamingwolf-upbq]

Thank you Brian I've learn so much from your videos, you teach way better that my math teachers.

What grade level is this cause I’m doing it on my 8th grade NWEA test where I have to use this algorithm then find the three basic trig functions anyways this vid was very useful

[bp_cherryblossomtree]

Do you have a video that explains in a sentence,
ex: Two angles of a triangle measure (36 and (102) One of the side formed by the (36) angles is (9) (inches) long

[humancentered]

Would be important to title this with “90 degree triangle” because this is the only shape this works for

[anime_jacksparrow]

Nice video today i learn something new all the best💝

[FatheredPuma]

I'd say at 2:15 for the real world it ends. You'd just square root 104 and get 10.2m.

[nevaehtaylor]

does anybody know what grade he is teaching im just curious lol

[emilymccloud]

Really helps i dont understand my teachers rocket science. This easy

[chiche]

THX!!! Helped me a lot during the test!

[sumanvishwakarma]

thanks for helping me with mathematics 😊🙃😀🤗😄
