The triangle area will be greatest if the base equals to diameter. The height will become very small. So the area = (1/2)(base x height) ~ (1/2) x base = (1/2) x 2 = 1
Bia
Still don't understand...
Please Help..
Thanks...
Can someone put a little more light to this question..

This can be proven but for GMAT purpose just remember that an isosceles triangle has max area when angles are 90-45-45.. In this case area of this triangle is
0.5*1*1 = 0.5 = 1/2
Ans B
PS: I am sure this answer would not convince you but this rule can help
0.5*1*1 = 0.5 = 1/2

As was stated above, the area is greates when the base = 2, or the diameter of the circle.
If you split this large triangle into two right triangles, you end with two triangles with base and hight 1 and hypotenus of sqroot2.
Therefore, the larger triangle has hypotenus (diameter) 2 and base and height sqroot 2.
Area = sqroot2 x sqroot2/2 = 2/2 = 1.
