## What is the 2 tangent theorem?

The Two-Tangent Theorem states that if two tangent segments are drawn to one circle from the same external point, then they are congruent.

### How many tangents can 2 circle have?

when considered two circles. 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.

#### How do you prove two tangents are equal?

Hint: First draw a circle with two tangents touching it with the same external point then join the points touching the circle and the center and atlast join the center of the circle to the external point, you will get two triangles trying to prove them congruent to get the required result.

**Can two tangent lines intersect inside a circle?**

No tangent line can be drawn through a point within a circle, since any such line must be a secant line. However, two tangent lines can be drawn to a circle from a point P outside of the circle.

**How many tangents can draw 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.

## How many common tangents do 2 disjoint circles have?

This lesson will talk about number of common tangents to two given circles….Lesson Summary.

Position | Number of Common Tangents |
---|---|

Touching externally | 3 |

Intersecting at two points | 2 |

Touching internally | 1 |

One lying inside other | 0 |

### What does mutually tangent mean?

Circles are “mutually tangent” when each pair of them touch at a single point. At that point their common tangent will be perpendicular to the line that joins their centers.

#### How many times can two tangent lines intersect in a circle?

A line can only intersect a circle 0, 1, or 2 times: twice for chords and secants; once for tangents.

**How to solve tangent circles?**

Find the point where the tangent to the circle with equation (x^2 + y^2 = 20) at the point (2, 4) crosses the x-axis. Draw a diagram to show the circle and the tangent at the point (2, 4) labelling this P. Draw the radius from the centre of the circle to P. The tangent will have an equation in the form (y = mx + c)

**What is the two tangent theorem?**

## What is the tangent of two circles?

Tangent To A Circle. A tangent to a circle is a straight line,in the plane of the circle,which touches the circle at only one point.

### What is a tangent circle theorem?

The following are the properties defining tangents to a circle.
