Are all polygons 4 sided?
A polygon can have any number of sides. Polygons with more than four sides aren’t as common as triangles and quadrilaterals, but they’re still worth knowing about. Larger polygons come in two basic varieties: regular and irregular. A regular polygon has equal sides and equal angles.
Which statement is always true about a regular polygon?
For a polygon to be ‘regular’ it must have all sides the same length and all interior angles the same.
What is a polygon with 4 uneven sides?
Quadrilaterals are polygons with four sides (hence the beginning “quad”, which means “four”). A polygon with non-equal sides is called irregular, so the figure that you are describing is an irregular quadrilateral.
What does a regular polygon have to have?
A polygon is called regular if it has equal sides and angles. Thus, a regular triangle is an equilateral triangle, and a regular quadrilateral is a square.
Does a polygon have to have all 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….Regular polygon.

What are the properties of a four sided polygon?
Kite: Two pairs of adjacent sides are of equal length; the shape has an axis of symmetry. Irregular Quadrilateral: a four-sided shape where no sides are equal in length and no internal angles are the same. All internal angles still add up to 360°, as with all other regular quadrilaterals. A five-sided shape is called a pentagon.
Are there names for polygons with many sides?
There are (ridiculous) names for polygons with many more sides (see wikipedia:Polygon ), but generally for larger numbers of sides, one uses the number of sides followed by “-gon”. We talk about 7-gons and 8-gons for instance (instead of the harder to remember names heptagon or octagon).
How many sides does a regular pentagon have?
A regular pentagon has 5 equal sides and all the interior angles measures to 108 degrees. A polygon with an irregular shape. It means the sides and angles of the polygon are not equal. A quadrilateral with unequal sides.
What’s the difference between regular and irregular polygons?
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.
