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 missing lengths in a circle using tangent theorems.
--I can find missing lengths or angles in a circle involving 2 tangents that intersect at a point using Pythagorean Theorem or trig ratios.
--I can find missing lengths in a circle involving a radius and a tangent line using Pythagorean Theorem.
--I can identify and define different types of angles and arcs in a circle.
--I can identify an give precise definitions of: arc, central angle, major arc, minor arc and semicircle.
--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): Unit #3 Right Triangle Trig test analysis (attached below).

Direct Instruction/Guided Practice:
--Review bellringer and homework (tangent lines practice)
--Guide students in completing Arcs foldable (attached below).

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.
--Students will complete arcs and angles vocabulary with Central Angles & Arc Lengths graphic organizer (attached below) and central angles w/s attached below.
