Answer
coterminal;
$360^o$;
$2\pi$
Work Step by Step
RECALL:
(1) Two angles whose initial sides and terminal sides are the same are called coterminal angles.
(2) The coterminal angles of a given angle can be found by adding or subtracting multiples of $360^o$ or $2\pi$ to the measurement of the angle.
Thus, the missing expressions in the given statements are (in order):
coterminal;
$360^o$;
$2\pi$
