What is a common tangent?
Definition of Common Tangent A tangent to a circle is a line that passes through exactly one point on a circle and is perpendicular to a line passing through the center of the circle. A line that is tangent to more than one circle is referred to as a common tangent of both circles.25 mar. 2021

How many types of common tangent are there?
There can be four common tangents to two circles. The tangents can be either direct or transverse. When the two circles neither intersect nor touch each other, there are four common tangents. But when they intersect there are two common tangents, both of them being direct.
How do you know if two circles are tangent?
Two circles are tangent to each other if they have only one common point. Two circles that have two common points are said to intersect each other. Two circles can be externally tangent if the circles are situated outside one another and internally tangent if one of them is situated inside the other.23 fév. 2012
What is tangent for circles?
A tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency.
What is tangent segment?
A tangent segment is a segment with one endpoint at the point of tangency and its other endpoint somewhere on the tangent line. A tangent segment is also perpendicular to the radius of the circle whose endpoint is the point of tangency.
Does radius bisect a tangent?
In a circle, perpendicular from center to the tangent is always radius ( or diameter) of the circle. In a special case, it may bisect tangent (only if it is a line segment) spreading equally in both sides from the contact point.
That is because a common tangent it perpendicular to the the radius, and for any three circles to have a common tangent, their radii, at the point of tangency must either be co-linear or be parallel, which is impossible in a scenario for all radii at the point of tangency for all the three circles.
What is the point where two circles meet?
Two circles may intersect in two imaginary points, a single degenerate point, or two distinct points. The intersections of two circles determine a line known as the radical line.
How do you find the common tangent length of two circles?
The length of a direct common tangent to two circles is √d2–(r1–r2)2, where d is the distance between the centres of the circles, and r1 and r2 are the radii of the given circles.
