What 2D shapes are irregular?
An irregular shape is one without equal sides or equal angles. Some examples of irregular shapes are: right-angle triangle, irregular pentagon, irregular hexagon, quadrilateral, etc.
What is the name for an irregular shape?
polygons
Irregular shapes (or polygons) are often much harder for children to name because they don’t look like the more conventional regular shapes. In fact, they can be any straight-sided shape.
What is a 2D shape example?
2D shapes are shapes with two dimensions, such as width and height. An example of a 2D shape is a rectangle or a circle. 2D shapes are flat and cannot be physically held, because they have no depth; a 2D shape is completely flat.
Is circle an irregular shape?
Regular means predictable, with the fewest possible variations. 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.
What are irregular objects examples?
Those substances which do not have a fixed geometrical shape are called irregular objects. Some of the examples of irregular objects are the pieces of broken glass, a piece of stone, a broken piece of brick, leaf, etc.
Is Kite a 2D shape?
shapes (2D) 2D shapes have only 2 dimensions and are flat e.g. square, rectangle, triangle, circle, pentagon, hexagon, heptagon, octagon, nonagon, decagon, parallelogram, rhombus, kite, quadrilateral, trapezium.
Is a star an irregular shape?
By geometrical definition, a star is a regular polygon: simple or complex. Polygon – any two-dimensional shape formed with straight lines and is closed. Regular polygon – a polygon whose sides are all the same length (equilateral) and whose angles are all the same (equiangular).
Is Oval a 2D shape?
An oval shape is a 2D closed geometric shape with no straight lines or vertices. It is a curved figure with one flat face that resembles the shape of an egg.
Is a cone a 2D shape?
A cone is a 3D shape consisting of a circular base and once continuous curved surface tapering to a point (the apex) above the centre of the circular base.
Is trapezium a 2D shape?
2D shapes have only 2 dimensions and are flat e.g. square, rectangle, triangle, circle, pentagon, hexagon, heptagon, octagon, nonagon, decagon, parallelogram, rhombus, kite, quadrilateral, trapezium.

| Kite | Unequal angles Although 2 pairs of sides are equal, not all 4 are equal. |
| Irregular quadrilateral (more examples) | Not all 4 angles are equal; Not all 4 sides are equal |
