Study Notes
Angle Measurement Units
- Converting degrees to radians: Multiply the degree measure by $\frac{\pi}{180}$.
- Converting radians to degrees: Multiply the radian measure by $\frac{180}{\pi}$.
-
Submultiples of degrees: Minutes (') and seconds (") are used to express angles more precisely.
- 1 degree = 60 minutes
- 1 minute = 60 seconds
Congruent Arcs and Least Positive Determination
- Congruent arcs: Two arcs are congruent if they have the same measure.
-
Finding the least positive determination: To find the least positive determination of an angle:
- For degrees: Keep adding or subtracting 360° until the angle is between 0° and 360°.
- For radians: Keep adding or subtracting 2π until the angle is between 0 and 2π.
- Representing angles on the unit circle: Visualization helps understand trigonometric functions and their relationships.
