This is a review lesson. We will have our final exam next Sunday.

Students should review what we have learned this semesters by going over their homework.

We review the properties of circles.

In the symmetry properties category, we have the following:

• Equal chords are  equidistant from the center;
• The perpendicular bisector of a chord passes through the center;
• Tangents from an external point are equal in length;
• The line joining an external point to the center bisects the angle between the tangents

In the category of angle properties, we have:

• Angle in a semicircle is a right angle;
• Angle between tangents and radius is a right angle;
• Angle at the center is twice the angle at the circumference;
• Angle in the same segment are equal;
• Angle in opposite segments are supplementary.
