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.
- Students will make flashcards on Circle Vocabulary and Circle Theorems from Quizlet.
- Students will do the Learn, Write, and Match activities on Quizlet for these two sets of terms.
