Question 9

Use the diagram to complete the statements.

Revolt · Accepted Answer

We are given that angle AOB is a central angle of circle O and that angle ACB is a circumscribed angle of circle O. We see that AO ≅ BO because .: all radii of the same circle are congruent; We also know that AC ≅ BC since .: tangents to a circle that intersect are congruent; Using the reflexive property, we see that .: side CO is congruent to side CO; Therefore, we conclude that △ACO is congruent to △BCO by the .: SSS congruency theorem
