Area of a circular segment and a formula to calculate it from the central angle and radius. Including a calculator The Intersecting Secants Theorem, states that: If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment. A secant of a circle is a line connecting two points on the circle. When two nonparallel secants are drawn, a number of useful properties are satisfied, even if the two intersect outside the circle. These properties are especially useful in the context of cyclic quadrilaterals, as they often allow various angles and/or lengths to be filled in. In fact, these results are so useful that it is Displaying top 8 worksheets found for - Circles And Secants.

The angle formed by the intersection of 2 tangents, 2 secants or 1 tangent and 1 secant outside the circle equals half the difference of the intercepted arcs! Therefore to find this angle (angle K in the examples below), all that you have to do is take the far intercepted arc and near the smaller intercepted arc and then divide that number by two! In Geometry, secant lines are often used in the context of circles. The secant line below, in red, intersects the circle with center O, twice.
