Quick Answer: What Is A 4 Sided Irregular Shape Called?

What is a 4 sides shape called?

Four-Sided Polygons – Quadrilaterals The term tetragon is consistent with polygon, pentagon etc.

You may come across it occasionally, but it is not commonly used in practice.

The family of quadrilaterals includes the square, rectangle, rhombus and other parallelograms, trapezium/trapezoid and kite..

Does a diamond have right angles?

Bring in some new friends. They’ll probably say you have a diamond on your wall. But a diamond also has four equal sides and right angles at the corners.

Is any 5 sided shape a Pentagon?

In geometry, a pentagon (from the Greek πέντε pente and γωνία gonia, meaning five and angle) is any five-sided polygon or 5-gon. … The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting.

Is a star an irregular shape?

In geometry, a star polygon is a type of non-convex polygon. Only the regular star polygons have been studied in any depth; star polygons in general appear not to have been formally defined, however certain notable ones can arise through truncation operations on regular simple and star polygons.

What is an irregular four sided shape called?

What is an irregular quadrilateral? Irregular quadrilaterals are: rectangle, trapezoid, parallelogram, kite, and rhombus. They are symmetrical, but are not required to have congruent sides or angles.

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 are the 4 properties of a rhombus?

Properties of RhombusAll sides of the rhombus are equal.The opposite sides of a rhombus are parallel.Opposite angles of a rhombus are equal.In a rhombus, diagonals bisect each other at right angles.Diagonals bisect the angles of a rhombus.The sum of two adjacent angles is equal to 180 degrees.More items…•

What is a 20 sided object called?

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

Is Circle an irregular shape?

Is a circle a regular shape or an irregular shape? … So yes, a circle is about as regular as a shape can be. You can define a circle with just a center and a radius. Compare this, for example, to the shape of a human body, which would be rather irregular, requiring a lot of information to describe it fully.

Is a rhombus an irregular shape?

A regular polygon must be equilateral (all of its sides are the same length) and equiangular (all of its angles are the same measure). A rhombus is equilateral: all of its sides are of the same length. … A rhombus can never be a regular polygon because it is not equiangular.

How many 4 sided shapes are there?

sixThere are six different types of quadrilaterals: parallelogram, rectangle, rhombus, square, kite, and trapezoid.

What is a irregular shape?

An irregular shape is a shape which has sides and angles of any length and size.

Does a rhombus have 4 90 degree angles?

Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).

What is a 10 sided shape?

In geometry, a decagon is a ten-sided polygon or 10-gon.

What is a 9 sided shape called?

enneagonIn 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 do you call a rectangle with uneven sides?

A quadrilateral is a square if and only if it is both a rhombus and a rectangle (i.e., four equal sides and four equal angles). Oblong: a term sometimes used to denote a rectangle that has unequal adjacent sides (i.e., a rectangle that is not a square). Kite: two pairs of adjacent sides are of equal length.

What’s a 12 sided shape called?

dodecagonIn geometry, a dodecagon or 12-gon is any twelve-sided polygon.
