A name which has nothing to do with this question (well almost nothing)

What percentage of the circle is shaded? (The quadrangle shown in the picture is a square with one of the vertices in the circle's center.)

25% because the square forms a 90 degree angle and 360/90=4 and if you treat 360 as 100%, 25 goes into 100 4 times, and 90 goes into 360(which is a full circle) four times, thus the answer being 25%
