Intersection Of Two Circles
Bayani Gaba-gaba
Two circles can miss each other, touch at a single point, or cross at two. Finding where they meet looks daunting, because each equation has squared terms, but a single subtraction sweeps the squares away and leaves a straight line: the common chord. From there the problem becomes the familiar line-meets-circle.
In this lesson you will subtract one circle equation from the other to find the line through the intersection points, substitute back into a circle to find the points themselves, and use the number of solutions to decide whether the circles intersect, touch or miss.
Manufura
- Solve problems involving the intersection of two circles, including finding points of intersection and the equation of a common chord, and determining whether two circles intersect, touch or do not intersect.
