1. CONTINUITY
and INFINITY with Circles
A. Construct a
circle through three points.
What do you think
will happen to the center F of the circle as A moves?
What do you think
will happen to the circle when A is near and on and past BC?
Watch what happens
to the circle as you move point A past BC.

B. PROVE that if two
minor arcs of different circles have the same chord BC, the longer arc is in
the circle with the smaller radius.
