# What are concentric circles in geometry?

You’ve probably seen concentric circles before – they’re circles that have a common center point. But what does that mean in terms of geometry? Let’s take a closer look.

In geometry, concentric circles are two or more coplanar circles with a common center point. That means that the circles are all in the same plane, and they share a center point. The word “concentric” comes from the Latin roots con-, meaning “together,” and -centric, meaning “center.” So when we say that two things are concentric, we mean that they share a center point.

Concentric circles can be of any size – the only requirement is that they share a common center point. That means that you could have two concentric circles, one inside the other, or you could have several concentric circles with different radii. You could even have two parallel lines that are concentric, as long as they share a common center point!

## Conclusion

Concentric circles are a type of coplanar circle – meaning that they share a common center point. Concentric circles can be of any size, and they can be used to create interesting patterns and designs. So next time you see a set of concentric circles, you’ll know exactly what it is!

## FAQ

### What is concentric circle example?

A concentric circle example is two or more circles with a common center point. The circles can be of any size, and they can be in the same plane or different planes.

### What is a concentric shape?

A concentric shape is a shape that has a common center point. The term is most often used in geometry to describe two or more circles that share a center point, but it can also be used to describe other shapes, such as parallel lines.

### What are the properties of concentric circles?

The properties of concentric circles are that they share a common center point and that they arecoplanar. Concentric circles can be of any size, and they can be in the same plane or different planes.
