Unit 3—Circles and Spheres
MA1G3. Students will understand the properties of circles.
a. Understand and use properties of chords, tangents, and secants as an application of triangle similarity.
b. Understand and use properties of central, inscribed, and related angles.
c. Use the properties of circles to solve problems involving the length of an arc and the area of a sector.
d. Justify measurements and relationships in circles using geometric and algebraic properties.
UNIT ESSENTIAL QUESTION: What measurements can I make on curved shapes?
