Chord is a line segment in a circle where the endpoints lie on the circumference. [br][br]The angle between a tangent TC and chords is the same as the angle in the alternate segment.
After your observation, you can conclude that angle CBA is _____________ to angle TCA.
When you move point T around and make the angle TCA = 50[math]^\circ[/math], what is the degree for angle CBA?
