What is the measure of a complete angle?
A complete angle is one whose value is 2π or 360°, it is formed by a straight line after rotating it from initial position to back to its initial position.
Hence, the measure of a complete angle is s 2π or 360°.

(a) Two line segments are congruent if __________.
(b) Among two congruent angles, one has a measure of 70°; the measure of the other angle is __________.
