Hi Everyone,

Thanks for the very useful discussion here. I understood the property of diameter being the hypotenuse.
Please excuse my asking this extremely basic question (it must be a forgotten property), how do we know if the base is AB or BC?

Also, a super basic question for my learning.
Why are we taking hypotenuse = 1
Diameter is 2(r) = 2
Shouldn't we take:

1/2 *b*h
= 1/2 *sqrt(3) *2
= sqrt(3)

Thanks!

Your first doubt is addressed here: https://gmatclub.com/forum/in-the-figur ... l#p1803640

Your second doubt is not clear. The radius = 1, so the diameter, AC, which is also the hypotenuse is 2.
