i have the worst geometry teacher. he does care at all. thank you for explaining this clearly

[@tonydeabreu1876]

This video was explained better than my teacher! Thank you very much

[@DarrenthePopKidz]

Too bad my mathematics questions are not as colourful as this... ;-P

[@jamesjosephclarke]

I really like just looking over these videos to brush up on some of the basic maths even though I'm in year 12. Thanks a heap Sal!

[@gabriellefulford9063]

Does anyone know what website or app he uses to make these videos? Like how to get the blank screen and be able to draw with different colors and stuff?

I have one question, how do you know in what order to put the angles in, like abc acb bca because that's the thing that really throws m off

[@wyattdudey]

Whatever letter is in the middle is the angle you are referring to. I’m not sure about the first and third letter but for angle C at the beginning it could be in the bigger or smaller so you’d say Angle ACB so you know you are referring to angle C in the bigger triangle. I hope that makes sense and helps.

[@tmeares21]

helps so much thankyou!

[@beat_music_with_prem_]

You Are Amazing🙏🙏🙏🙏

[@ninjapenguin1039]

I have a question... for the second problem, shouldn't you be able to cross multiply DE/4 by 3/5 instead of having to do the whole equation that you showed?

[@josephbloncourt3834]

I am getting confused about this. It is hard to explain in this manner though but I will try: When I set up the equivalent proportions for the triangles I am usually wrong which numbers to use. How do I know for sure which side number to use to set up equivalent proportions?

[@PaulPriz]

Hi Sal, I think the comment @ 7.29- 6 2/5 - 4 2/5 =2 2/5 is incorrect. Regards

[@antonelloc4864]

the unkown is at the denominator
