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 identify and describe parts of a circle including: circumference, radius, diameter, chord, secant, and tangent.
--I can identify a tangent line and solve problems involving tangent lines.
--I can identify/name a central angle and identify/name its intercepted arc.
--I can identify the intercepted arc for an inscribed angle.
--I can find measures of inscribed angles and their intercepted arcs in a circle.
--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.

Introduction/Connection (Bellringer): None.


Direct Instruction/Guided Practice:
--students will complete quiz on circle vocabulary, tangent lines, central and inscribed angles in Progress Learning.

Independent Practice/Collaboration/Differentiation:
--Independent practice:
--students will complete quiz on circle vocabulary, tangent lines, central and inscribed angles in USA Test Prep.
--Differentiation: all testing accommodations as outlined in 504s and IEPs.

Summarizer/CFU: review line segments and theorems (central angle, inscribed angle, tangent) prior to quiz using round robin.

Assignment: TBA.
