## How do you classify a polygon?

So, what is a polygon? A polygon is a closed sided figure, formed by three or more segments that never cross. And we can further identify it’s type as either convex, concave or regular. A convex polygon is when no line that contains a side of the polygon includes a point in the interior of the polygon.

## What are polygons Khan Academy?

A polygon is a closed figure with at least 3 straight sides.

What are the three classifications of a polygon?

The different types of polygons are:

• Concave polygons (at least one of the interior angles is greater than 180°)
• Convex polygons (all the interior angles are less than 180°
• Regular polygons (all the sides and angles measure the same)
• Irregular polygons (all the sides and angles measure different)

### What is a polygon PDF?

A polygon is a shape with straight sides. It is a Greek word that literally means many-angle. The parts of a polygon. The straight lines of a polygon are called edges or sides. The corners are called vertices.

### How do you determine if a figure is a polygon?

The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon. A shape that is not fully closed is not a polygon.

Can polygon Have curves?

A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons – a polygon, by definition, is made up of straight lines.

## What I have learned in polygons?

Lesson Summary We’ve learned that a polygon is a flat shape with straight sides. A regular polygon has all its sides and angles equal. An irregular polygon does not have all sides and angles equal. A convex polygon has all angles pointed outwards and less than 180 degrees.

## What are polygons explain different of polygons?

A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.

What are the properties of polygons?

When working with polygons the main properties which are important are:

• The number of sides of the shape.
• The angles between the sides of the shape.
• The length of the sides of the shape.
