A teacher couldn't teach me this over two weeks. You taught me in 5 minutes. Why isn't America bleeding its finances over to this guy.

Good video. Although, if I am to be picky, the Area=(1/2)(base)(height) DOES work for all triangles, but finding the height is an extra step if it isn't a right triangle. The Area=(1/2)*a*b*sin(C) calculates the height within the formula.

You have saved me from failing geometry. Thank you

Thank You so MUCH!!! You are the BEST at explaining and you work through every step making it easy to understand! Thank you so much. Keep up the good work!!!

This channel is AWESOME!!! It made my maths so easy!!! Thank you Vivid maths!!

[VividMath]

Good question! All you have to do is first use the sine rule to find another side.( to use sine rule you need 2 angles and one side) . Now you have two sides, so you can use the above formula to find the area, hope that helps. :)

wish i had a teatcher like you when i was young great job sir

[PWskates]

great video; teaches complex subjects in a simple manner!

Thank you so so much this vidio should have got so many more likes 10 years late

[calliehinson]

This helped me ace my test! Thanks, man!

[sonjamogorosi]

thank you so much my teacher never explained the formula used to calculate the area of a non right angled triangle, now I known how to do it .THANK YOU

[elimarburger]

you can use the formula 1/2 bh for any triangle that is quite misleading

[beyblade]

So it's basically 1/2ab x sin(angle?

[Alienmohno]

Thank you so much !! I really understand it

[fsxurdu]

Thanks a lot for being so detailed,
Can i ask 2 things???
1. Can i divide this equilateral triangle from center and then calculate it as right angle triangle??
2. Can i write the formula as A=1/2absin??

Looking ahead for your kind guidance

[mukeshkumar]

I like this formula but i couldn't find your website. is it active or not???

THANK U SO MUCH U SAVED ME FROM MY REVIEW OF LONG TEST!!! I USED LAW OF SINES THEN DOING 1/2abSinC then the answer wasn't in the choices! It was just 1/2acSinB!!!!THANM U SO MUCH DUDE

[shubhtube]

I am in 8th grade, and I don't understand sin and the formula, but helped me lil' bit.

you have saved my math test for tomorrow! thank you!
