How do you find the angle formed by a chord?

If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle . In the figure, m\u22201=12(m\u2322QR+m\u2322PS) .

What is a tangent-chord?

Tangent: A tangent to a circle is a line, ray, or segment that touches the outside of the circle in exactly one point. It never crosses into the circle. A tangent can't be a chord, because a chord touches a circle in two points, crossing through the inside of the circle.

What is the relationship of a second and a tangent intersecting in the exterior of a circle to its intercepted arc?

When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.

Which angle is formed by the two tangents?
