## How do you find the point where two circles touch?

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.

## What is tangent in drawing?

A tangent is **a line in the plane of a circle that intersects (passes through) the surface of a circle**. The point where the line passes through the surface of the circle is called the “point of tangency”. The line is called the “tangent line” but is referred to mainly as the “tangent”.
