   US Common Core State Standard Math HSG-C.A.2
Demonstrations 1 - 20 of 21

Description of Standard: 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.     The Bomb Problem The Sum of Opposite Angles of a Quadrilateral in a Circle is 180 Degrees Geometric Elements of a Circle Thales's Theorem: A Vector-Based Proof Euclid, Book 3, Proposition 22     Inscribed and Central Angles in a Circle The Perpendicular Bisector of a Chord A Product of Chord Lengths in a Circle The Chordal Theorem Inscribed Angles That Intercept the Same Arc     Tangent Circles Equally Distant Chords Tangents to a Circle Tangent Chord Angle Intersecting Secants Theorem     Intersecting Chords Theorem Circles & Triangles Three Points Determine a Circle Inscribed Angles in a Circle Subtended by the Same Chord Thales' Theorem
