Solve mathematical and real-world problems involving the measures of arcs and related angles.
Clarifications
Clarification 1: Within the Geometry course, problems are limited to relationships between inscribed angles; central angles; and angles formed by the following intersections: a tangent and a secant through the center, two tangents, and a chord and its perpendicular bisector.General Information

MFAS Formative Assessments
Central and Inscribed Angles:
Students are asked to describe the relationship between a central angle and an inscribed angle that intercept the same arc.
Circles with Angles:
Students are given a diagram with inscribed, central, and circumscribed angles and are asked to identify each type of angle, determine angle measures, and describe relationships among them.
Inscribed Angle on Diameter:
Students are asked to find the measures of two inscribed angles of a circle.
