Learning Goal: Introduce relationships of segments of circles through reasoning and exploration. Then, focus on chords and explore their relationships.

Classwork

• Estimation – Circle
• Warm Up
  • Taken from New Visions
• Notes
• Go over Concept Quiz
  • Students complete analysis handout in order to prepare for retake. See retake policy and learning folders post for more details.

Standards

• Common Core
  • HSG.C.A.2 – Identify and describe relationships among inscribed angles, radii, and chords. 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.
• TEKS
  • G.12(A) – apply theorems about circles, including relationships among angles, radii, chords, tangents, and secants, to solve non-contextual problems
