What are the different types of tangents?
The following are a list of tangent types:
- • Fixed.
- • Flat.
- • Linear.
- • Smooth.
- • Smooth Normal.
- • Plateau.
What are the two types of tangent?
A line which is tangent to more than one circle is called a common tangent. The tangents can be classified into common tangents that are internal and external. An internal tangent is a line segment, which passes through the centre of the two circles whereas the external common tangents do not.
How do you define tangent circles?
A line that touches the circle at a single point is known as a tangent to a circle. The point where tangent meets the circle is called point of tangency. The tangent is perpendicular to the radius of the circle, with which it intersects.
How many tangents are in a circle?
infinite tangents
A circle can have infinite tangents. Such lines are called tangent lines or simply as tangents to the circle from a given point. It may be noted that from a particular point outside a circle only two tangents can be drawn.
What is a four common tangent?
If two circles do not touch or intersect each other and one does not lie inside the other, they will have four common tangents. AB and CD are called direct common tangents, and MN and XY are called transverse common tangents.
How many common tangents are in circle?
In most cases, two circles have four common tangents.
How many common tangents are there?
There can be three tangents in common. The one tangent will be at the point of touching where the two circles are touching each other. The point of contact of both the circles. The second tangent will be at the bottom which will touch both the circles.
What is common internal and external tangent?
Common tangents to two circles may be internal or external. A common internal tangent intersects the line segment connecting the centers of the two circles whereas a common external tangent does not.

What is the definition of tangent in geometry?
In Geometry, the tangent is defined as a line touching circles or an ellipse at only one point. Suppose a line touches the curve at P, then the point “P” is called the point of tangency. In other words, it is defined as the line which represents the slope of a curve at that point.
What is a tangent point?
tangent, in geometry, the tangent line to a curve at a point is that straight line that best approximates (or “clings to”) the curve near that point. It may be considered the limiting position of straight lines passing through the given point and a nearby point of the curve as the second point approaches the first.
What is a three common tangent?
4. Three Common Tangents: If two circles touch each other externally at one point, they will have three common tangents.
What are internal and external tangents?
Two circles in the same plane are internally tangent if they intersect in exactly one point and the intersection of their interiors is not empty. Two circles in the same plane are externally tangent if they intersect in exactly one point and their intersection of their interiors is empty.
What is transverse common tangent?
Direct and transverse common tangent The direct common tangents meet on the line passing through centres and divide it externally in the ratio of the radii. The transverse common tangents meet on the line passing through centres and divide it internally in the ratio of the radii.
How many tangents can a circle have?
A circle can have infinite tangents. But a set of two lines can pass through the circle by just touching it at one and only one point. Such lines are called tangent lines or simply as tangents to the circle from a given point. It may be noted that from a particular point outside a circle only two tangents can be drawn.
What are the properties of tangents?
Properties of Tangents
- The tangent line never crosses the circle, it just touches the circle.
- At the point of tangency, it is perpendicular to the radius.
- A chord and tangent form an angle and this angle is same as that of tangent inscribed on the opposite side of the chord.
What is called tangent?
What is external tangent?
DEFINITION: External tangents are lines that do not cross the segment joining the centers of the circles.
