On properties of circles, their chords, inscribed angles, tangents and secants see the lessons
- A circle, its chords, tangent and secant lines - the major definitions,
- The longer is the chord the larger its central angle is,
- The chords of a circle and the radii perpendicular to the chords,
- A tangent line to a circle is perpendicular to the radius drawn to the tangent point,
- An inscribed angle in a circle,
- Two parallel secants to a circle cut off congruent arcs,
- The angle between two chords intersecting inside a circle,
- The angle between two secants intersecting outside a circle,
- The angle between a chord and a tangent line to a circle,
- Tangent segments to a circle from a point outside the circle,
- The converse theorem on inscribed angles,
- The parts of chords that intersect inside a circle,
- Metric relations for secants intersecting outside a circle and
