Circle theorems: foundations

Problem

A circle has center O. P and Q are points on the circle, and line segments connect each point to O, forming angle POQ. Angle POQ measures 135 degrees and corresponds to minor arc PQ.
The circle has center O, and the measure of angle POQ is 135. The length of minor arc PQ is what fraction of the circumference of the circle?
(The number of degrees of arc in a circle is 360.)
