This concept teaches students how to calculate angles formed outside a circle by tangent and secant lines, using formulas and examples. The radius of a circle allows for the determination of its diameter, circumference, and area, and can be used to calculate the surface area and volume of an associated object. Students can also find the measure of central, inscribed, interior, and exterior angles of a circle using intercepted arcs, central angles, inscribed angles, tangent chord angles, and more.
An angle is considered outside a circle if its vertex is outside the circle and its sides are tangents or secants. There are various types of angles, such as an angle formed by two tangents or an angle formed by two rays. To find the measure of angles in circles, students can use intercepted arcs, central angles, inscribed angles, tangent chord angles, and more.
The derivation of the formula relates arc lengths to the angle of lines that intersect outside of a circle. The circumference of a circle is its outside edge, and the distance from the center to any point on its length is called the radius. The circumference and diameter of a circle are related by the relationship C = 2πr, and by extension, by the relationship C = πD.
In conclusion, this concept teaches students how to calculate angles formed outside a circle by tangent and secant lines, find the lengths of secant and tangent intersecting in the exterior of a circle, and quickly find segment lengths (chords, tangents, and secants) for circles.
