Guy used a computer program to create the drawing below. He then used a tool on his program that allowed him to move point B around the circle. Each time he stopped, he recorded the measurement of angle BAC (the tangent chord angle) and the intercepted arc in a table.
Which conjecture is supported by the information in the table?

The answers
The measurement of the tangent chord angle is one half that of the intercepted arc.
The measurement of the inscribed angle is one half of the intercepted arc.
The measurement of the tangent chord angle is the same measurement as the intercepted arc.
The measurement of the tangent chord angle is twice that of the intercepted arc.
