area of a sector of a circle formula (theta has to be in radians)

a=1/2r^2(theta)

for a circle with radians, to find coterminal angles use the formula

angle(+-)2pi

for a circle with degrees, to find coterminal angles use the formula:

angle(+-)360

coterminal angle

angles that share a terminal side

how to convert degrees to radian

degrees x pi/180

for converting degrees to times ..

keep numbers before decimal the same then divide the decimal by 60 and then divide the decimal of the answer to the last question by 60

angles that create our quadrants are called

quadrantal angles

how to convert radians to degrees

radians x pi/180

arc length formula

s=r(theta)
