In Rho-Theta notation, what does Theta represent?

• A. Distance
• B. Angle
• C. Bearing
• D. Speed

Answer: (B)

Rho-Theta notation locates a point using distance and direction. The first value, rho, is how far from the origin. The second value, theta, is the angle that tells you which direction around the origin to go, measured from a reference axis (typically the positive x-axis, with counterclockwise being positive). So theta represents the angular position or orientation, not distance, speed, or a bearing from north. For example, a point with rho = 5 and theta = 60 degrees is 5 units from the origin and lies 60 degrees from the reference axis.
