I just started Geometry this year and have been completely lost, until I found your videos. I've been watching them and have actually been able to understand the concepts and bring my grades up. You're a wonderful teacher and I am eternally grateful!! Thank you so much!!

[@nebmasterflash3705]

Great Video! I have been a fan for some years now and I appreciate everything you do for the struggling kids like me. You have made my scores go up so much!

[@b_alexis0945]

Thank youuuu, I finally get a better understanding

[@user-kd4bv6zo1w]

This, as I know, is the most important topic. It helped me solve a lot of complex geometry problems!

[@gastonpierrelau8652]

I have a test tomorrow and this really helps

[@giulianadavila6517]

Game changing math video! 😎

تسلم يا حج والله انقذتني

[@artwithanvil]

Thank you so much! Your the reason I understand geometry. My grades have gone up a lot after watching your videos! Do you have a video explaining two collum proofs? Those have been difficult for me. Once again thank you so much you don't understand how much I appreciate you!

[@MariosMathTutoring]

Yes I do! You can check my geometry playlists but here is one example: 2 Column Triangle Congruence Proof AAS

You are the man, looked for help on exams this week and this did the trick

[@MariosMathTutoring]

Awesome!

[@glarify9190]

I have a quiz tomorrow and I finally understand now after watching this video. Thank you and I will be subscribing!

[@MariosMathTutoring]

Glad I could help!

[@beanz4383]

Thank you for the amazing video that you have provided you have given me a much better understanding of what I was not able to understand in my own Geometry class environment I am truly grateful that I was able to find your channel to understand what I am learning in a better way.

[@MariosMathTutoring]

Glad my video helped you!

[@mitchlaber7723]

Try Trisolve.

[@obbyperson7281]

for quesiton number 9 (er) how do you know the base are both congruent because it isnt marked and i dont know if i should look judge off of how it looks. (reflexive property)

[@teshomemamo9398]

Thank you teacher

[@MariosMathTutoring]

You are welcome!

[@kimballclark1392]

So the consecutive angle theorem must be a bi-conditional if you use the converse to solve the problem.

[@schnauk_3427]

Great video 👍

[@MariosMathTutoring]

Thanks 👍

[@joshxzy]

can example 8 also be ASA?

[@luheepark8748]

What grade level math is this?

[@anzumanararunu1343]

We should promote these hard work as much as possible.

[@giulianadavila6517]

how do you deal with parallel lines crossing triangles?😕

[@Goldbotanic]

What do I put if the congruent triangles only show the angles?

[@MariosMathTutoring]

Just knowing the angles and nothing else is not enough to prove the triangles are congruent.

[@violethill4454]

this is so hard

[@MariosMathTutoring]

May I ask what part about it is difficult?

[@josephthebroseph7421]

@@MariosMathTutoring yes
