    In this section of MATHguide, you will learn about the various sections there are related to circles and their properties.

    This sections serves as the primer for learning about circles. It is necessary to know critical terms so that the relationships and equations can be understood. MATHguide has this lesson to teach you about the terminology.

    This section of MATHguide will inform you about angles at the center of circles and the arcs they intercept.

    An inscribed angle is an angle that has its vertex on a circle and its sides are chords of the same circle. This lesson will inform you of the relationship between these angles and the arcs they intercept of the circle.

    There are two relationships related to chords, one for lengths of partial chords and the other for arcs and the angle subtended by those arcs. View this lesson to access explanations for both of those relationships.

    This section deals with properties related to intersecting secant lines and the circles they also intersect. A picture of intersecting secant lines can be seen here.
