Altitude of a Triangle - Finding The Orthocenter

This geometry video tutorial provides a basic introduction into the altitude of a triangle. It provides the definition of an altitude and it includes plenty of examples of finding the orthocenter of an acute triangle, right triangle, and an obtuse triangle.

You’re the best! You explain things better than a professor or a book.

MR. Organic Chemistry Tutor, thank you for another exceptional video/lecture on Altitude of a Triangle - Finding the Orthocenter in Solid/Analytic Geometry. This topic is strictly visual, so drawing the triangles is the first step that all students should focus their attention, in order to find the Orthocenter.

Thank you soo much you dont know how long i have been looking for a video that explained all 3 types of triangles

[iamrks]

You continued to say "median" instead of "altitude" in this video. I assume you meant "altitude" of the three vertices.

[braxma]

1:32 Please correct! Not medians, altitudes!! you mistake everywhere the word median with altitude.

[cupcakes]

THANK YOU! DIS IS DA BEST EXPLANATION SO FAR! HONESTLY!!!

[jam_sam_]

big thanks! u are better than my teacher

[alial-musawi]

Suddenly, you started to talk about the 'medians'. I hope you were meaning to say 'altitude'.

[sweetysharma]

thanks alot....it was a great help....
love from INDIA😊

[Dikucc]

I didn't learn from any other videos but learnt from your video

[Sssrone.-hpgx]

Thanks you made me understand it better 🥰😍🤩😁😁😁😄

Sir in an obtused angled triangle, if we extend the base in order to find the altitude; which is considered and base and why

[ts]

thank you so much!
but could you help me with this doubt:
there is a property regarding orthocenters that "The orthocenter divides an altitude into two different parts and the product of the lengths of these two parts of an altitude is equal for all three perpendiculars." is this aplicable even for a right angled triangle could you provide an example. Regards

Error: You said whenever you draw three medians when you meant to say three altitudes.

[annabrubaker]

Mr. Al-Musawi is right. You started using the term "medians, " when we are talking about "altitudes." I point my geometry students to your videos to review the concepts I teach at their own convenience. I can't use this video now because they are special needs students, and they will get massively confused because you interchange the words "median" and "altitude." Can you fix this?

[naiooo]

thank you so much I have a final tomorrow and this helped a lot

[kabouch]

1:34, you certainly mean " three altitudes"

[chandniaswani]

Isn't median a segment joining vertex of a triangle to the mid-point of the opposite side? An altitude is not the same as a median, then why does he keep calling it medians?

[ExoRides]

imma be 100% honest i dont think anyone is gonna buy a $49 hoodie from random math tutor on youtube. just sayin

[Brlvhan]

lord if u hear me you will let me pass my test today what are these WORDS
