## What is the condition for two circles touch externally?

You may be asked to show that two circles are touching, and say whether they’re touching internally or externally. To do this, you need to work out the radius and the centre of each circle. If the sum of the radii and the distance between the centres are equal, then the circles touch externally.

## How many tangents can be drawn to 2 circles touching externally?

3 common tangents
⇒ There are 3 common tangents can be drawn for two externally touching circles.

Can be drawn to two circles touching internally?

Answer: When two circles touch each other internally 1 common tangent can be drawn to the circles.

When two circles touch externally distance between their centres difference of their radii state whether the given statement is true or false?

Therefore, we can say that if two circles touch externally, then the distance between their centres is equal to the sum of their radii. Hence the correct answer for this question is option (b).

### What is the intersection of two circles called?

The intersections of two circles determine a line known as the radical line.

### How many tangents can be drawn from a point outside the circle?

two 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 tangents can be drawn to two intersecting circles?

two common tangents
Only two common tangents can be drawn to two intersecting circles.

How many common tangents can be drawn to two circles which touch internally solve the following?

Answer. Answer: Only one common tangent can be drawn to two circles which touches internally.

## How many tangents can be drawn to the circle from a point which lies external of circle *?

two tangent lines
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.

## When two circles touch externally distance between their centres difference of their radii?

Therefore, we can say that if two circles touch externally, then the distance between their centres is equal to the sum of their radii.
