What’s a 2D shape?
2D shapes have sides and corners, and are completely flat. Watch the video to learn all about 2D shapes, like circles, triangles, squares, rectangles, pentagons, hexagons and octagons!
What are 2D and 3D shapes examples?
Example: square, rectangle, circle, etc. Example: cube, cuboid, sphere, etc.
Difference Between 2D and 3D Shapes.
| Area | Surface Area |
|---|---|
| Plane 2D figures represent the area. Example: circles, rectangles, and triangles. | Solid 3D figures represent the surface area. Examples: cylinder, prisms, pyramids, and cones. |
What are the examples of 3D shapes?
Some examples of the 3D shapes are a cube, cuboid, cone, cylinder, sphere, prism and so on. The 3D shapes consist of both curved shaped solid and the straight-sided polygon called the polyhedron.

What is a 2D and 3D shape?
A two-dimensional (2D) shape has only two measurements, such as length and height. However, a three-dimensional (3D) shape has three measurements, such as length, width, and height. One example of a 3D shape is a rectangular prism, which is made up of four rectangles and two squares.
What are shapes with 3 sides called?
Triangles. The most basic shape with straight sides is the triangle, a three–sided polygon. You find out all about triangles when you study trigonometry. Triangles are classified on the basis of their sides and angles.
What is a 9999 sided shape called?
What do you call a 9999–sided polygon? A nonanonacontanonactanonaliagon.
What is a 100 sided shape?
In geometry, a hectogon or hecatontagon or 100-gon is a hundred–sided polygon. The sum of all hectogon’s interior angles are 17640 degrees.
What are 4 sided shapes called?
A quadrilateral is a four–sided two-dimensional shape. The following 2D shapes are all quadrilaterals: square, rectangle, rhombus, trapezium, parallelogram and kite.
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.

What is a 10 sided shape called?
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.
What is 11 sided shape called?
In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon.
What is a 50 sided shape called?
In geometry, a pentacontagon or pentecontagon or 50-gon is a fifty-sided polygon. The sum of any pentacontagon’s interior angles is 8640 degrees. A regular pentacontagon is represented by Schläfli symbol {50} and can be constructed as a quasiregular truncated icosipentagon, t{25}, which alternates two types of edges.
What is a 7 sided shape?
A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… Polygon Names. The names of polygons are derived from the prefixes of ancient Greek numbers.
What is 8 sided shape called?
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight–sided polygon or 8-gon.
What is a 7 sided 2D shape called?
In geometry, a heptagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using “sept-” (an elision of septua-, a Latin-derived numerical prefix, rather than hepta-, a Greek-derived numerical prefix; both are cognate) together with the Greek suffix “-agon” meaning angle.
