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 apply the following theorems when solving problems involving chords:
--Two minor arcs are congruent if and only if their corresponding chords are congruent.
--If a diameter of a circle is perpendicular to a chord, then the diameter bisects the chord and its arc.
--If one chord is a perpendicular bisector of another chord then the first chord is a diameter.
--Two chords are congruent if and only if they are equidistant from the center.

Introduction/Connection (Bellringer): None.

Direct Instruction/Guided Practice:
--Review Circle Puzzles #1 & #2 h/w (1st block only)
--Finish chord theorems foldable.
--Guide students in selected problems on Chord Theorem w/s (attached below).

Independent Practice/Collaboration/Differentiation:
--differentiation: Graphic organizers with cloze notes, foldables, color coding lines/segments, one-on-one assistance for struggling students, accelerated practice for higher performing students, partner work, student-led teaching/review.
