These "segments" may be chords, other portions of secants, and/or portions of tangents. The formulas for the lengths of these segments will be investigated. If two chords intersect in a …

Line a does not intersect the circle at all. Line b intersects the circle in two points and is called a SECANT. Line c intersects the circle in only one point and is called a TANGENT to the circle. …

The three theorems for the intercepted arcs to the angle of two tangents, two secants or 1 tangent and 1 secant are summarized by the pictures below. If you look at each theorem, you really …

Oct 21, 2024 · When two chords intersect “inside” a circle, four angles are formed. At the point of intersection, two sets of vertical angles can be seen in the corners of the X that is formed on …

Jan 6, 2026 · Secants, chords, and tangents are all lines that uniquely relate to a circle. Learn about the angles, arcs, and related formulas here!

Identify, describe and apply relationships among radii, chords, tangents, and secants of a circle. Include algebraic problems built upon these concepts. Copyright © 2004-now JMAP, Inc. - All …

Jan 1, 2026 · Recall that the product of the outer portion of a secant and the whole is equal to the same of the other secant. If one of these segments is a tangent, it will still be the product of the …

Theorem 85: If a tangent segment and a secant segment intersect outside a circle, then the square of the measure of the tangent segment equals the product of the measures of the …

A line will meet a circle at no more than two points. We call a line a secant if it intersects twice, and a tangent if it intersects once (just touching at a single point). Chords are segments …
