Circles & Arcs
This program defines the term circle and how to find angle measures for central angles and arcs. The distance formula is used to find the length of a radius on a graph and the midpoint formula is reviewed in order to find the coordinates of the center of a circle on a graph. Perpendicular bisectors are also used in this lesson to find the center of a circle. Students will Learn: Diameter, Radius, Arc (minor, major, semicircle), Central Angle, Chord, Tangent, Secant.
