  • Conterminal angels are angles with the same initial and terminal  sides. However, the rotations could be different hence the co-terminal.
  • Reference angel is the smallest positive acute angle formed by  terminal side of the angle t and horizontal x axis. (Blitzer, 2021)
• Find the Reference angle of the following : I will find by adding or subtracting 360 from the given angle ,  

=

• Find the Conterminal angle of the following :  I will find by adding and or subtracting 

or  

• -

= +

• , first you need a common denominator to add or subtract. 
• =

+=-=

• Find the following refence and conterminal angels:
