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:
LT: I can find missing angles and arcs involving tangents, chords and secants of circles.
SC:
--I can identify a chord, secant and tangent line of a circle.
--I can apply the appropriate theorem based on the relationship of given segments including:
--Tangent-secant (angle on the circle)
--Secant-secant (angle outside of the circle)
--Chord-chord (angle inside the circle)

Introduction/Connection (Activator): students will complete #1-6 on attached w/s central/inscribed angle w/s.

Direct Instruction/Guided Practice:
--review bellringer whole group
--Introduce/guide students in angle relationships between tangent/secants, secant/secant and chord/chord using attached graphic organizer (Secants and Tangents) and foldable.
--Guide students in solving for missing angles involving secants, tangents and chords using attached foldable Angles formed by Secants Tangents foldable.

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