# What is a polygon with 3 sides called?

## What is a polygon with 3 sides called?

Triangle. A polygon with 3 angles and 3 sides.

What shape has 3 sides that are equal?

Triangles
Three-Sided Polygons: Triangles Equilateral – all the sides are equal lengths, and all the internal angles are 60°.

### What do you call the polygons with equal sides?

In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex or star.

What things have 3 sides?

A triangle has 3 sides and 3 corners. A corner is where two lines meet or join. There are different kinds of triangles.

#### What is a polygon with 3 vertices and 4 sides?

This point is called a vertex of the polygon. In the polygon there are as many vertices as there are sides. The triangle has 3 sides and 3 vertices. The quadrilateral has 4 sides and 4 vertices.

What kind of polygon that has 3 sides and 3 angles?

triangle
A polygon has as many angles as it has sides. For example, a triangle has 3 sides and 3 angles. A pentagon has 5 sides and 5 angles.

## How can polygons be similar?

Two polygons are similar if their corresponding angles are congruent and the corresponding sides have a constant ratio (in other words, if they are proportional). Typically, problems with similar polygons ask for missing sides.

Which is an example of a polygon with three sides?

The point where two line segments meet is called vertex or corners, henceforth an angle is formed. An example of a polygon is a triangle with three sides. A circle is also a plane figure but it is not considered as a polygon, because it is a curved shape and does not have sides or angles.

### How are polygons classified according to their symmetries?

Polygons are also classified according to their symmetries. A regular polygon is one in which all sides are equal length and all angles are of equal magnitude. An irregular polygon is one in which the sides and angles are unequal measures. For example, a square is a regular quadrilateral. The angles and sides of a square are all equal.

What’s the difference between a triangle and a polygon?

The line segments of a polygon are called sides or edges. The point where two line segments meet is called vertex or corners, henceforth an angle is formed. An example of a polygon is a triangle with three sides. A circle is also a plane figure but it is not considered as a polygon, because it is a curved shape and does not have sides or angles.

#### How are the sides and angles of a polygon determined?

Every polygon has an equal number of sides and vertices. Thus, every polygon has an equal number of vertices and angle. For any simple polygon, the sum of its interior angles can be determined by the formula:
