If the difference between two angles is \(1980^\circ\) can they be coterminal?
#trigonometric-functions
#coterminal-angle
#error-checking
A हाँ क्योंकि अंतर बड़ा है / Yes because the difference is large
B हाँ क्योंकि \(\frac{1980}{360}\) पूर्णांक है / Yes because \(\frac{1980}{360}\) is an integer
C नहीं क्योंकि \(1980^\circ\) सम कोण नहीं है / No because \(1980^\circ\) is not an even angle
