What You Need To Know...

MAFS.912.G-C.1.2 - Identify and describe relationships among inscribed angles, radii, and chords.

1. The benchmark will be assessed using Equation Response, Graphic Response, Multiple Choice Response, Multi-select Response, Open Response, or Simulation Response.

2. Items may require student to solve problems related to circles using the properties of central angles, inscribed angles, circumscribed angles, diameters, radii, chords, and tangents.

3. Items may require students to find or describe the length of arcs when given information.

Example One

The circle shown below is centered as the origin and contains the point (-4, -2).
