Determine the sides of a triangle produce an acute, obtuse or right triangle

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 inequality 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.

Thanks so much this helped me get 100 on my math test

[taarini]

why am i learning from this guy on youtube then my actual math class?
see this is why more youtube is good XD no but for real tho

[hodor]

My homework is complete thanks to you :)

[samanthachoate]

Thanks Brian McLogan...I have twin boys in high school and you are my favorite youtube teacher. So simple and clear. Thanks for helping us all here to learn!!!

[kafia]

Do you have any videos on how to find it without the Pythagorean Therom?

[h.gracee]

wow. Some people can explain it so easily. tysm. My math teacher explained it horribly lol

[jaysuth]

You are a great teacher. Thanks so much for this video. My daughter needed help with this and I am WAY out of practice. We were able to figure it out in a minute or two.

What if 2 sides are equal?
(example: 7, 3, 10)

Thank you so much for this video, I surely would have failed my test if you didn’t have this video up for us struggling students.

[fatimatariq]

What an amazing video. It's Brief but elaborated 👍.

[yarashiry]

When I saw what was written at 1:40 I solved my homework right away I hope that I solved it correctly when I come back tomorrow from school i'll write in the comments whether if it was correct or incorrect ! Thanks for your help btw you seem like a great teacher (;

[NomanKhan-imze]

Sir could u plzz u tell me if its acute or obtuse? Sides: 17, 10, 21

[ckphoss]

I learned more about this kind of paragraph in my book from him instead of my teacher explaining it 2 lessons and still nobody understands😂😂

[blopppppppp]

what if for example 1-1-1, is it still a triangle?

[rual]

in other videos grether than is obtuse less than is acute which is right

[MsAmberB]

Did you notice your exponent mistakes? C needs an exponent and 100 does not need an exponent.

[toothytoad]

lol, he messed up on the obtuse equation twice. once by not putting the square sign on "c", and then twice by sayinig "100 squared".
