What 3 characteristics make a polygon?
We can identify a polygon by checking the following characteristics in a shape:
- It is a closed shape, that is, there is no end that is left open in the shape.
- It is a plane shape, that is, the shape is made of line segments or straight lines.
What are the 3 polygons?
List of n-gons by Greek numerical prefixes
| Sides | Names | |
|---|---|---|
| 3 | trigon | triangle |
| 4 | tetragon | quadrilateral |
| 5 | pentagon | |
| 6 | hexagon |
Does a polygon have 3 or more sides?
A polygon is any shape whose sides are all straight. Every polygon has three or more sides (if it had fewer than three, it wouldn’t really be a shape at all). Following are a few of the most common polygons.
What are the 5 properties of a polygon?
- Side – one of the line segments that make up the polygon.
- Vertex – point where two sides meet.
- Diagonal – a line connecting two vertices that isn’t a side.
- Interior Angle – Angle formed by two adjacent sides inside the polygon.
- Exterior Angle – Angle formed by two adjacent sides outside the polygon.
What is a polygon for kids?
Any closed two-dimensional shape with three or more sides is called a polygon. Polygons can be regular or irregular. The sides and angles of a regular polygon are all equal. An irregular polygon has at least two sides or two angles that are different.
How many polygons do we have?
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….Definition of a Polygon.
| Shape | # of Sides |
|---|---|
| Octagon | 8 |
| Nonagon | 9 |
| Decagon | 10 |
| n-gon | n sides |
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.
What is a polygon with 5 vertices and 3 sides?
Pentagon
| Pentagon | |
|---|---|
| An equilateral pentagon, i.e. a pentagon whose five sides all have the same length | |
| Edges and vertices | 5 |
| Internal angle (degrees) | 108° (if equiangular, including regular) |
What are the parts of a polygon?
The parts of polygons include the sides, interior angles and exterior angles. There is also the vertex, the spot where two sides meet, and the diagonals, or lines connecting vertices.
What is a polygon shape?
A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A polygon. A shape with curved sides is not a polygon.
