Question 256042: hiya
I wanted you to tell me the proof that altitudes on a triangle are congruent using Ceva's theorm. But i nned to know the proof using trigonmetry.
the diagram i was given was of a triangle ABC and a line that is perpendiular to the line BC (at point A')and hits vertex A. also i have an angle at A*B*A' 'b'.
Could you help me please? thanQ for looking

I don't think you meant 'congruent.' I think you meant 'concurrent.' See the Wikipedia article on Ceva's Theorem:
