Positive Coterminal Angle
x + 2π = Positive Coterminal
34
Negative Coterminal Angle
x - 2π = negative coterminal
35
Complementary angle (90°)
theta + x = π/2
36
Supplementary angle (180°)
theta + x = π
37
Radian to degree measure
Rad/π = x/180
38

Arch length
theta/360 = x/2π r
40
Area of a sector
theta/360 = x/π r^2
41
Radian measure of arch length
x/360 = arch length/2π r
42
Radian measure of Central angle
theta = arch length/ r
