# Geometric Flat Shapes: Characteristics and Types Geometric flat shapes are a complex of points, lines, bodies, or surfaces. These elements are two-dimensional elements that can be placed both on a flat plane forming a finite number of lines.

The basic geometric shapes are points and curved or straight lines. They are located on the plane. In addition to them, among the simple shapes distinguish a ray, a broken line and a segment.

## What Are the Basic Flat Shapes?

• The point is the basic element of any plane figure. It is very small, but it is always used to build various shapes on the plane. The point is the main figure of absolutely all constructions, even the most complex ones.

• The straight line is completely in the same plane. Straight lines consist of a large number of points located on an infinite line, which has no limits or boundaries.

• A vertex is the point where two straight lines meet in a geometric figure.

• A quadrilateral is a flat geometric figure that has 4 edges and four vertices. Some examples of quadrilaterals are: the square, the rectangle, the parallelogram, the rhombus, and the trapezoid.

• A polygon is any geometric figure composed of three or more straight lines joined by vertices to form a closed shape.

## What Are the Main Flat Shapes?

• The circle consists of a curved line in which each point on the circumference is the same distance from a point (the center).

• The triangle is made up of three sides and three vertices.

• The square is made up of four sides of the same length with four 90º angles.

• The pentagon is made up of five sides and five equal angles.
