Frequently Asked Questions

How is depth achieved in this unit?

Depth in this unit is achieved by providing the chance to reengage with similarity (Unit 3) as students prove all circles are similar, the length of the arc intercepted by an angle is proportional to the radius, and define the radian measure of the angle as the constant of proportionality.  Time permitting, further depth can be achieved by extending each big idea. The properties of circles can be extended to include tangent lines. Constructions can be extended to inscribed and circumscribed circles of a triangle. Deriving equations can be extended to parabolas and finding the area of a sector.
