Can anyone pls help.
this one is pretty easy...

you are told that one angle is formed at the center and that the other two angles are formed from points on the circle, and that the radius is 1.

area triangle = 1/2(b)(h)

b = 1
h = 1

therefore, 1/2(1)(1) = 1/2

Okay - I know this is not a GMAT level concept - but - thats how it was obvious to me that its shpuld be a right triangle =>
Formula : The area of any triangle is ½ absinC
a=b=r=1 in this case and the max value of sinC is 1 when C is 90 degrees.
=> right triangle with area => ½ *1*1*1 => 1/2

and, since it is on GMAT prep => there has gotta be a simpler explanation => pls help !!
