Geometry, Two Column Proofs of Angles - Addition, Substitution & Transitive Property
This geometry video tutorial provides a basic introduction into two column proofs with angles. It covers the addition and subtraction property of equality as well as the substitution and transitive property of congruence. It also covers vertical angles, angle supplements and more. This video contains plenty of examples and practice problems on angle proofs.

MR. Organic Chemistry Tutor, thank you for another excellent video/lecture on Geometry Two Column Proofs of Angles- Addition, Substitution and Transitive Property. Learning the two column proofs can also be confusing, however constant practice and memorizing theorems and definitions are very helpful.
Not only was this very helpful, but your voice is quite soothing, but not boring. Thank you, this really helped
This is the only video on proofs that actually helped me
can this also be called a congruent supplements theorem: two angles that are supplementary to the same angle are congruent?
Your channel is so awesome for my science and math classes. Special place in heaven for you omg
A wonderful and simple explanation. Thanks!
I HAVE A GEOMETRY TEST LATER, THIS IS SO MUCH HELP THANK YOUUU
your videos are really helpful to me, thank you!
Life saver I have a test in an hour.
Thank you for another great video. Wondering if you could use a yellow marker instead of blue, blue is hard to see against the black screen. Thank you so much for your thorough explanations.

9:37, step three, the reason " angle addition" you can also classify it as "the whole is equal to the sum of it's parts" based on what state you're in!

Angelina T. You can prove they’re parallel because the given is angle 1 is congruent to angle 4.
6:20
that was extremely helpful :) thank you so much for your help. buttttt i not sure if i did this right but i was solving the second question on my own and got a different answer hence you could not automatically assume that 2 is congruent to 3 from 1 being congruent to 4 even though it may be common sense to automatically assume that it doesn’t prove that with any actual reasoning, what i did for that problem was i put all the givens then i set angle one plus angle two equal to angle three plus angle four, using the supplement theorem. then you would substitute the four out for the three making it angle one plus angle two equals angle one plus angle three, lastly you would just get rid of the ones because there congruent. and you would get the final answer of angle two is congruent to angle three :) i know there are multiple ways to solve it but i don’t think that the said problem was explained well enough just jumping from angle 1 is congruent to angle 4 then assuming that angle 2 is congruent to angle 3
Sooooooo Helpful, Thanks!!!!
You are a lifesaver!
Why do they make it so complicated in writing proofs? You could just literally write, 'Angle 1 is congruent to angle 3' in statements. Then "Definition of Alternate Exterior Angles" for reasons. Bam done!

Hi. I need your help. You mentioned in the minute 10:14 that the property is Substitution. What is the difference between Substitution and Transitive property?
@michelle-xu9zh
Жыл бұрын
transitive property is when a=b, b=c, therefore a=c so for example, AB+BC=90 a. b CD + DE=90 c. d AB+BC = CD+DE a. c this is how transitive property might work in a problem. substitution is when you are only replacing one part of the equation. AB=BC AB=CD this could be an example for substitution, atleast to my understanding (if anyone wants to correct me then pls feel free!!)
@carmencruz5673
Жыл бұрын
@@michelle-xu9zh thanks, I saw other videos and I thinks that I understand now. In this video is substitution because as you said, replace one part of the equation. Example: AB=90 CD=90 Then I replace 90 with the other value, and obtain: AB=CD Transitive applies between successive members of a sequence, it must also apply between any two members taken in order. For instance, AB=CD CD=EF Then AB=EF
