Finding lines tangent to a circle
WebMar 11, 2024 · In the case of a line that is tangent to a graph, you can use the point (x,y) where the line touches the graph. If you use that x and that y and the slope m, you can use algebra to find c. y=mx+c, so, c=y-mx. Once you have c, you have the equation of the line! Done. Thanks! We're glad this was helpful. Thank you for your feedback.

WebA tangent is a line that intersects the circle at one point (point of tangency). A common tangent is a line, ray or segment that is tangent to two coplanar circles. Tangents to Circles Examples: You are standing 14 feet from a water tower. The distance from you to the point of tangency on the tower is 28 feet. What is the radius of the water tower? WebJan 16, 2015 · Let O be the intersection point between the line through the centers and the tangent.. Let d be the distance between the centers and h1, h2 be the distances between O and the centers. By similarity, these are proportional to the radii. Hence, h1 / h2 = r1 / r2 = m, h1 + h2 = d, giving. h1 = m d / (1 + m), h2 = d / (1 + m).
