## How do you determine the measures of the angle formed by the intersection of two chords two secant segments intersecting at the point in the exterior of the circle?

If two secants intersect inside a circle, then the measure of the angle formed is equal to half the sum of the measures of the intercepted arcs.

## How do you find the angle of two intersecting Secants?

If two lines intersect outside a circle , then the measure of an angle formed by the two lines is one half the positive difference of the measures of the intercepted arcs . In the circle, the two lines ↔AC and ↔AE intersect outside the circle at the point A .

How do you solve intersecting secants?

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.

When two chords intersect each other inside a circle the products of their segments are equal?

If two chords intersect in a circle , then the products of the measures of the segments of the chords are equal. In the circle, the two chords ¯AC and ¯BD intersect at point E . So, AE⋅EC=DE⋅EB .

### How do you find the value of intersecting lines?

How Do I Find the Point of Intersection of Two Lines?

1. Get the two equations for the lines into slope-intercept form.
2. Set the two equations for y equal to each other.
3. Solve for x.
4. Use this x-coordinate and substitute it into either of the original equations for the lines and solve for y.

### What is the intersection of two angles?

The intersecting lines can cross each other at any angle. This angle formed is always greater than 0o and less than 180o . Two intersecting lines form a pair of vertical angles. The vertical angles are opposite angles with a common vertex (which is the point of intersection).

How do you find the intersecting secants outside the circle?

When two secants intersect outside a circle, the circle divides the secants into segments that are proportional with each other. Two Secants Segments Theorem: If two secants are drawn from a common point outside a circle and the segments are labeled as below, then a(a+b)=c(c+d).

What points does each secant intersect the circle?

In the case of a circle, a secant intersects the circle at exactly two points. A chord is the line segment determined by the two points, that is, the interval on the secant whose ends are the two points.

## What is intersecting chords in music?

Intersecting Chords. Products of segments of intersecting chords are equal. If two chords intersect inside a circle, then the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.
