Standards Addressed:
MGSE.9-12.G.C.2 Identify and describe relationships among inscribed angles, radii, chords, tangents, and secants. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle.

Learning Targets /Success Criteria:
--I can find measures of missing inscribed angles and their intercepted arcs in a circle.
--I can identify the intercepted arc for an inscribed angle.
--I know that the measure of an inscribed angle is half the measure of its intercepted arc.
--I know that the intercepted arc of an inscribed angle is twice the measure of the inscribed angle.
--I can use the fact that a circle is 360 degrees and semicircles are 180 degrees to find missing arcs and angles involving inscribed angles.
--I can find measures of missing central angles or arcs in a circle.
--I can identify that circles are 360⁰.
--I can identify that semicircles are 180⁰

Introduction/Connection (Bellringer): students will start Circle Puzzle attached below.

Direct Instruction/Guided Practice:
--Review bellringer
--Review inscribed angles w/s and h/w from Thursday (if needed)
--Guide students in completing w/s distinguishing between central and inscribed angles.

Independent Practice/Differentiation/Collaboration:
--differentiation: Graphic organizers, foldables, color coding lines/segments, one-on-one assistance for struggling students, accelerated practice for higher performing students.
--Independent practice: students will complete IXLs listed on Thursday and Central and inscribed angles puzzle (special rule w/s attached below).

Summarizer: TOTD

Assignment: Central & Inscribed Angles special rule w/s (attached below) OR IXLs listed from Thursday.
