SteveOh, dude, you're hitting me with some math here. So, a full circle is 360 degrees, right? So, if an angle measures 100 degrees, it's like turning a little less than a third of the way around the circle. So, that angle turns through about 100/360, which simplifies to 5/18 of the circle. Math is fun, right?

What fraction of the circle is 45 degrees?
There are 360 degrees in a circle so 45 degrees is 1/8th of a circle.
What fraction of a circle is 180 degrees?
A half.
What fraction of a circle is 270 degrees?
1 / 6
If W is the center of the circle and arc XZ measures 52 degrees what is the measure of angle XYZ?
26 degrees
How many degrees are in the arc of a circle?
A circle contains 360 degrees. Draw a circle, add a radius to any point on it, and then rotate the radius completely around. After it has returned to the point it initially intersected the curve, the radius will have rotated through 360 degrees.(another explanation, maybe no better.)A complete circle measures 360 degrees, so a half-circle is 180 degrees, a quarter-circle is 90 degrees and so forth. Another way to look at it is in terms of the central angle formed by the radii drawn from each endpoint of the arc - the measure of the arc in degrees is the same as the measure of this central angle in degrees.
