Updated on April 25, 2026
Convex – a straight line drawn through a convex polygon crosses at most two sides. Every interior angle is less than 180°. Concave – you can draw at least one straight line through a concave polygon that crosses more than two sides. At least one interior angle is more than 180°….
| Sides | Name |

Are equiangular polygons convex?
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.

Does a convex polygon have equal sides?
A regular convex polygon is a polygon where each side is of the same length, and all the interior angles are equal and less than 180 degrees. The vertices and sides are evenly spread around a central point.
Are equilateral polygons convex?
All regular polygons and edge-transitive polygons are equilateral. An equilateral quadrilateral must be convex; this polygon is a rhombus (possibly a square).
What is a polygon that is both equilateral and equiangular?
When a polygon is both equilateral and equiangular, it is called a regular polygon. A square is an example of a regular polygon.
What polygon has 13 sides?
Tridecagon
Tridecagon. A 13-sided polygon, sometimes also called the triskaidecagon.
Which is an equiangular and equilateral polygon?
An equiangular polygon is a polygon in which all angles are equal. An equilateral polygon is a polygon with equal sides. If both sides and angles are equal then the polygon is called regular. A square is both equilateral and equiangular (i.e. it is a regular polygon)
Which figure is equiangular and equilateral?
regular polygon
When a polygon is both equilateral and equiangular, it is called a regular polygon. A square is an example of a regular polygon.
Which of the following is an equiangular and equilateral polygon?
(a) In a square, all the sides and all the angles are equal. Hence, square is an equiangular and equilateral polygon.
Which polygon is equiangular and equilateral?
How many sides has a Nonagon?
9
Nonagon/Number of edges
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.
What is the difference between convex and equiangular polygons?
Equilateral polygons with more than four sides are also usually equiangular. If the sides are all the same length, then they also have the same angle measurement. This is not true, however, if one or more of their angles are ”pushed in,” like the red angle shown in the pentagon picture. This is the difference between convex and concave polygons.
What is the difference between regular polygons and equilateral polygons?
Regular- all angles are equal and all sides are the same length. Regular polygons are both equiangular and equilateral. Equiangular- all angles are equal. Equilateral- all sides are the same length.
Is a heptagon equilateral or equiangular?
This heptagon is both equilateral (seven equal sides) and equiangular (seven equal angles). As you can see, we can build larger polygons by adding more sides, and if we keep all of the sides the same length, they will be equilateral polygons.
What is the difference between equilateral and convex and concave?
Equilateral – all sides are the same length. Convex – a straight line drawn through a convex polygon crosses at most two sides. Every interior angle is less than 180°. Concave – you can draw at least one straight line through a concave polygon that crosses more than two sides. At least one interior angle is more than 180°.
