[spoiler]1/2[/spoiler]
It is a right triangle 1-1-sqrt2

So the area: (1x1)/2 = 1/2

hmmm, it would be isosceles thats for sure so height = 1.

yeah, the triangle should be equilateral because since the vertex is at the center, the diameter will divide the triangle in two haves having 90 degree angles at the bases. so base is 1 too.

(1*1) / 2 = 1/2
