The polar angle \(\theta\) is considered positive if … WebThe definition of an angle that measures 1 radians is that the arc that subtends (lies across from) said angle has to measure 1 radius. If the arc length across from an angle is less than 1 radius long, then the angle is less than 1 radians. If the arc length is longer than 1 radius, than the angle is more than 1 radians.
