Hypotenuse Leg Theorem - HL Postulate - Two Column Proofs

This geometry video tutorial provides a basic introduction into the hypotenuse leg theorem also known as the HL postulate. it's another triangle congruence theorem that helps you to prove that two right triangles are congruent to each other. This video focuses on geometry proofs using cpctc and two column proofs. It contains plenty of examples and practice problems.

My math teacher sucks all he does is sit around you have helped me and my grades so much thank you🙏🏻

[@stewberry7573]

Lol... Literally my teacher in Applied Chemistry

It is not that they are bad at the lesson it’s just they either are bad at explaining or the are lazy.. but sometime they might be bad at the lesson ;-;

That would be a downgrade for him. He has almost 3M nowww. So happy for him

MR. Organic Chemistry Tutor, thank you for another excellent video/lecture on the Hypotenuse Leg Theorem in Plane/Solid Geometry. This topic is not difficult to follow, however the Two Column Proofs of this type is different from the others, so attention must be paid to the different steps in the proof. I will rewatched and analyze this video from top to bottom.

[@sisterjimin-ahshalallifegu8211]

Lol when I seen his second example I was out in a flash helll naaaaa that’s some next level ish

[@mrwaltermath]

0:02 HL≅ Postulate Explanation
(0:50 Clarification: "H" stands for a pair of congruent hypotenuses, one in each diagram, and "L" stands for a pair of congruent legs, one in each diagram)
1:01 HL≅ Two Column Proof Example (with Perpendicular and Reflexive Property and CPCTC)
(1:35 Clarification: Writing it as segment CD is more appropriate than segment DC because A corresponds to C, see 3:24.)
6:26 HL≅ Two Column Proof Example (with Perpendicular and Reflexive Property and Radii and CPCTC)

Omg he’s so helpful I like his voice 🙃🌸

[@jadeknox5556]

I recommend watching this with no sound and only cc. It helps the brain store more info. But I also recommend audio and cc too. Ik cc is for people who are deaf but it also helps me who is adhd to pay attention

[@johnla3481]

Really helpful, and i know he will have some video on what you need help with

[@user-ii7uv5bt5y]

thx helped alot way beter then my math teacher

Thank you this video helped me a lot. :D

[@RahulSharma-ph1qu]

Thank you!

[@badsha5971]

Bro this helped so much keep up the amazing work

[@ronaldvelasco3464]

For example 1, can i say that the two triangles are congruent because of the definition of midpoint?

[@josesitocastorena341]

Thank you so much.

[@echin9372]

Perpendicular lines form congruent adjacent angles, the definition of perpendicular angles is that they form right angles.

[@H4rorrs]

still dont completely understand but the more i watch the more i start to get it

[@talalnedal9175]

thanks

How do tell in the reason if you should use HL Theorem vs HL Postulate. IT seems the same thing.

But what if it doesn't say that one line is perpendicular to another and only says that there's one given right angle in the first example

Can anyone help me? My teacher gave me a problem where I have never seen from any example ever. He only gave me two perpendicular lines as a given.

1:37 can it be AD is congruent to CD?

order doesnt matter

It does matter... it would not be congruent.. my math teacher said that

At 4:19, could you also say that AB is congruent to CB due to the definition of perpendicular lines?

[@aaaa-pr6wm]

Nope, you should have proven that B is the midpoint of line AC, then you could have AB is congruent to CB by definition of midpoint. You're being helped by an 11 year-old... Just sayin
