Subject AreaGeometry Honors
Grade Level8
Week #April 8-12
Unit of InstructionUnit 8: Circles with and without Coordinates
Standard(s) Taught

MAFS.912.G-C.1.2:  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.)

Learning Targets and Learning Criteria
  • identify central angles, inscribed angles, circumscribed angles, diameters, radii, chords, tangents and
  • use the sum of the measures of the central angels of a circle with no interior points in common is 360°.
  • describe the relationship between a central angle, inscribed angle, or circumscribed angle and the arc it intercepts.
  • recognize that an inscribed angle whose sides intersect the endpoints of the diameter of a circle is a right angle and that the radius of a circle is perpendicular to the tangent where the radius intersects the circle.
  • use Pythagorean Theorem to prove lines tangent to a circle at its radius.
