Angles Outside the Circle

50 Minute Class, Curriculum, Geometry

Learning Goal: Build understanding of how to determine measures of angles outside the circle and recap central & inscribed angles from the last few days.



  • 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
