Things to remember about CIRCLESchords, tangents, and secants OH MY!! All Radii are equal The diameter is the largest chord – it passes through the center. If the chords are congruent, the arcs are congruent If the arcs are congruent, the chords are congruent If the chords are parallel the arcs are congruent Formulas for finding the angle measure- Where is the vertex? (orange handout) Secant-Secant Rule (w * e = w * e) Secant Tangent Rule (w * e = t2)
