Quick Answer: What Is A Side Of A Polygon?

Is a polygon any shape?

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..

How do you find the missing angle of a polygon?

The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.

Is any 6 sided shape a hexagon?

In geometry, a hexagon (from Greek ἕξ hex, “six” and γωνία, gonía, “corner, angle”) is a six-sided polygon or 6-gon. … The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.

Does a rhombus have 4 right angles?

A Rhombus is a flat shape with 4 equal straight sides. Opposite sides are parallel, and opposite angles are equal (it is a Parallelogram). And the diagonals “p” and “q” of a rhombus bisect each other at right angles.

What is a one sided shape called?

Möbius stripIn mathematics, a Möbius strip, band, or loop (US: /ˈmoʊbiəs, ˈmeɪ-/ MOH-bee-əs, MAY-, UK: /ˈmɜːbiəs/; German: [ˈmøːbi̯ʊs]), also spelled Mobius or Moebius, is a surface with only one side (when embedded in three-dimensional Euclidean space) and only one boundary curve.

What is the minimum number of sides in a polygon?

3The least number of sides to form an enclosing figure is 3(Triangle). Hence at the minimum a polygon can have 3 sides. A polygon is a closed shape with 3 or more straight sides.

What is a polygon shape?

more … A plane shape (two-dimensional) with straight sides. Examples: triangles, rectangles and pentagons. (Note: a circle is not a polygon because it has a curved side)

What’s a 13 sided shape called?

tridecagonIn geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon.

Can a polygon have 2 sides?

In geometry, a digon is a polygon with two sides (edges) and two vertices. … A regular digon has both angles equal and both sides equal and is represented by Schläfli symbol {2}.

What is a 100 sided shape called?

hectogonIn geometry, a hectogon or hecatontagon or 100-gon is a hundred-sided polygon. The sum of all hectogon’s interior angles are 17640 degrees.

What’s a 20 sided shape called?

icosagonIn geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.

What is a polygon with 4 sides?

Four-Sided Polygons – Quadrilaterals Four-sided polygons are usually referred to as quadrilaterals, quadrangles or sometimes tetragons. In geometry the term quadrilateral is commonly used.

What is a shape that is not a polygon?

Triangles have 3 sides, squares have 4, pentagons have 5 and octagons have 8. A figure or shape is not considered a polygon if it has rounded sides or if its sides intersects at any place other than at the ends of each side. Therefore a circle is not a polygon and an hourglass shape is not a polygon.

How do you find the Apothem of a polygon?

More Formulas We can also use the area formula to find the apothem if we know both the area and perimeter of a polygon. This is because we can solve for a in the formula, A = (1/2)aP, by multiplying both sides by 2 and dividing by P to get 2A / P = a. Here, the apothem has a length of 4.817 units.

What is a 4 sided shape called?

quadrilateralPolygon. A quadrilateral is a polygon. In fact it is a 4-sided polygon, just like a triangle is a 3-sided polygon, a pentagon is a 5-sided polygon, and so on.

How many sides are in a polygon?

What is the formula of polygon?

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n – 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n – 2) * 180 / n.

What’s a 14 sided shape called?

tetradecagonIn geometry, a tetradecagon or tetrakaidecagon or 14-gon is a fourteen-sided polygon.

How do you find the area of a polygon?

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon’s center to the midpoint of any side that is perpendicular to that side.
