What is an irregular heptagon?
A heptagon is a seven-sided polygon. Along with seven sides, a heptagon has seven vertices and angles. A regular heptagon is a heptagon that has congruent sides and angles. An irregular heptagon is any heptagon with sides and angles that are not all congruent.

What is an irregular convex?
Definition: Any polygon that is not a regular polygon. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same.
What does irregular polygon mean?
That is, an irregular polygon is a polygon that does not have all sides of equal lengths and all interior angles equal. For example, consider this picture of an SD card: 5-sided Irregular Polygon. Notice the SD card has 5 sides and they are not all equal length. Also, the interior angles are not all equal.
What is irregular Dodecagon?
A dodecagon is a 12-sided polygon that encloses space. Dodecagons can be regular in which all interior angles and sides are equal in measure. They can also be irregular, with different angles and sides of different measurements.
What is an irregular Nonagon?
Irregular Nonagons An irregular polygon is a polygon with unequal sides and angles. An irregular nonagon is a nine-sided shape that does not have equal sides or angles. One real world example of an irregular nonagon is the US Steel Building in Pittsburgh, Pennsylvania.
What do you call a 7 sided shape?
Eight-Sided Shapes: In geometry, if a shape is two-dimensional and has straight sides, then it is called a polygon. There are many kinds of quadrilaterals. In geometry, a heptagon is a seven-sided polygon or 7-gon.
Is a rhombus regular or irregular?
A rhombus is an irregular polygon because although it does have 4 sides of equal length, it does not have equally sized angles.
What is irregular shape?
An irregular shape is a shape which has sides and angles of any length and size.
How do you know if a shape is concave or convex?
The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
