Using the geometric mean to determine the missing parts of a triangle

Learn about the geometric mean of numbers. The geometric mean of n numbers is the nth root of the product of the numbers. To find the geometric mean of n numbers, we first multiply the numbers and then take the nth root of the product.

I feel like my teachers goal is to explain everything as vague as possible, thank you so much

How does he not know for that square root of 285 can’t be simplified? It came from 15*19, whose prime factors are 3,5,19. It should be obvious.

Jose Paramo wow sorry i’m late but i deadass failed that test so i’m not gonna be any help to you. however if u look online try using the info in these videos to do worksheets and then check ur answer? idk that’s what i do if i don’t get what’s happening. good luck! :)

Thank you so much for this tutorial. I was having trouble with this unit in class because our teacher didn't fully explain why and how geometric mean works. I recongnized that there was something else to it other than JUST formulas, and thanks to you I understand that there is more to finding it. Thanks again!

Thank you so much! You saved me from my sub math teacher as my original math teacher was pregnant so he is the replacement and he cannot teach for his life! He just gave us handouts and expected us to know how to do stuff! I watched your videos on Sin Cosin and Tangent too and it was SUPER helpful! He didn't even tell us we need to put the calculator into degree mode! Although you may not see this, you are a savior to all students with bad teachers. Thank you so much!

What I found helpful in explaining this to my son was to keep the triangles all together and labeling which angles are congruent while still all in one triangle. Then explaining each opposite side of each congruent angle is proportional. Then when you separate the triangles it is easy to get the orientation they all represent. Your videos are great by the way and much better explanation then my sons teacher has. I had an awesome one back in the 1980s so I feel like he is being cheated.

[@lori6389]

Thank you for explaining this and making this video.. after watching this I understand it a lot more clear. When my teacher taught it to me he didn't explain it very well, but I know this will help me pass this test!!

[@eeeeeeee7774]

this is really helpful for me. My school is online this year, and honestly it sucks. They don't really teach us anything but definitions of theorems and then expect us to know how to do these things.

[@Leena02]

Thanks so much! Ur awesome!!

[@celestic6596]

Really helped me understand why the geometric mean works like that, thanks!

[@arhansarma6784]

What are the proportions to find the legs or the hypotenuse of a right triangle with geometric mean.

[@perry7003]

You can use the Pythagorean Theorem to find the leg/hypotenuse of a right triangle if you have two legs or one leg and the hypotenuse. Pythagorean Theorem: hypotenuse=sq rt of leg 1 squared plus leg 2 squared, or a squared plus b squared = c squared where a and b are the legs and c is the hypotenuse.

Sqrt(15×4) simplified is 2×sqrt(15) hope that helps (since 2 is the sqrt of 4)

[@hamiltonpotter4318]

What, so x is just like the height in finding the area of a triangle. If so this makes my life simpler. A guy in my class figured these out so my teacher wouldn’t explain and now we have to do them, so ya know cause I am scared of my teacher, youtube is a great resource

i’m confused my teacher didn’t tell me anything . how do you go from x= the square root of15 times 4. then it changes to x= 2 times the square root of 15

[@solaritus]

i'm sorry this is so late but it's called simplifying radicals. because within radicals if there's a perfect square with an integer root then you can place it to the left of the radical (in this case the sqrt of 4 is 2)
