# Surface in Geometry and Its 2 Types

Each solid body has one or more exteriors/faces , The exterior of the solid is called the surface in geometry. The surface has length and width but not height (negligible). So the surface is two dimensional.

## Definition of Surface in Geometry

Which has a length, width, but thickness is negligible and by which a solid is surrounded is called surface.

## Types of Surface

Planes are of two kinds. And they are – Flat Surface/ Plane and Curved Surface.

## Definition of Flat Surface Or Plane

A surface that is even or smooth, not high or low, is called a plane. Such as – the surface of the mirror, the pages of the book, the surface of the floor of the house.

## Definition of Curved Surface

A surface that is uneven or uneven is called a curved surface. Such as – football surfaces, stone roads.

## Properties of Surface

1. The surface has length and width. So it is two-dimensional.
2. The surface can be finite or infinite.
3. Each solid is bounded by a surface.
4. The surface can be turned into a curved surface or the curved surface into a plane.
