What is the relationship between a secant and a tangent?
A line that intersects a circle in exactly one point is called a tangent and the point where the intersection occurs is called the point of tangency. The tangent is always perpendicular to the radius drawn to the point of tangency. A secant is a line that intersects a circle in exactly two points.
How do you find the angles formed by secants and tangents?
If two secants, a secant and a tangent, or two tangents intersect in the exterior of a circle, then the measure of the angle formed is one half the difference of the measures of the intercepted arcs.
What is the relationship of a secant and a tangent intersecting on the exterior of a circle?
If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.
What is the tangent secant power theorem?
Secant-Tangent Power Theorem If a tangent and a secant intersect in the exterior of a circle, then the square of the measure of the tangent is equal to the product of the measures of the secant and its external secant segment. PM2=PN⋅PO.
What is the relationship between an angle formed by two secants two tangents or a secant and a tangent and its intercepted arcs?
Theorem: An angle formed by a TANGENT and a SECANT, TWO SECANTS or TWO TANGENTS intersecting outside a circle is equal to one-half the difference of the measures of the intercepted arcs.
How would you find the measure of the angle formed by two secants intersecting outside the circle?
If two secants intersect outside a circle, then the measure of the angle formed is equal to half the difference of the measures of the intercepted arcs.
What is the relationship of a secant and a tangent intersecting in the exterior of a circle to its intercepted arc Brainly?
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.
What is the relationship of two secants intersecting in the exterior of a circle to the measures?
