Intersecting Secants Theorem 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. Diameter: A chord that passes through the center of a Circle. A circle with centre \(C(a;b)\) and a radius of \(r\) units is shown in the diagram above. The word secant comes from the Latin word secare, meaning to cut. Two Secants Intersecting Formula: If two secant segments are drawn from a point outisde a circle, the product of the lengths (C + D) of one secant segment and its exteranal segment (D) equals the product of the lengths (A + B) of the other secant segment and its external segment (B). The segment BV is the measure of cot x. If two secants are intersecting inside a circle from a point, then the product of the secant length (A) and exterior part of that segment (B) equals the product of other secant length (C) and exterior part of that segment (D).

Calculations of the arc, length, radius and diameter make the process of figuring out the circle and the angle of it easier GoodCalculators. I want to be very clear, point A is not on the circle, point A is the center of the circle. Meaning: "a cutting," present participle of secare "to cut" (from PIE root *sek- "to cut"). Parent topic: Straight Lines. There’s also one for cotangents and cosecants, but as cotangents and cosecants are rarely needed, it’s unnecessary. Secant E and tangent T are shown in the diagram below as bold lines. Then PB PA = PD PC. The region bounded by the circle is also often referred to as a circle (as in when we speak of the area of a circle), and the curve is referred to as the perimeter or the circumference of the circle.
