The square, circle, and triangle are the most basic shapes on Earth, supporting structures both synthetic and natural.
Geometry is a branch of mathematics that studies the sizes, shapes, positions angles and dimensions of things. Flat shapes like squares, circles, and triangles are a part of flat geometry and are called 2D shapes.
A geometric shape is the geometric information which remains when location, scale, orientation and reflection are removed from the description of a geometric object. Such shapes are called polygons and include triangles, squares, and pentagons. Other shapes may be bounded by curves such as the circle or the ellipse.
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.
In Geometry, 3D shapes are known as three-dimensional shapes or solids. … 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.
A closed, two-dimensional or flat figure is called a plane shape. … A rectangle is a shape with four sides and four corners. They may notice that opposite sides are the same length. A square is a rectangle in which all four sides are of equal length. A circle is a round shape that has no sides or corners.
There are many shapes in geometry based on their dimensions. Circle, Triangle, Square, Rectangle, Kite, Trapezium, Parallelogram, Rhombus and different types of polygons are the 2-d shapes. Cube, Cuboid, Sphere, Cone and Cylinder are the basic three-dimensional shapes.
A triangle with all sides of equal length.
A triangle with two sides of equal length.
A triangle with no sides of equal length. That is, all sides have a different measure.
A triangle with a 90 degree angle and all sides of different length.
A triangle with a 90 degree angle and two sides of equal length.
A quadrilateral with four right angles and four sides of equal length.
A quadrilateral with four right angles.
A quadrilateral with two pairs of parallel sides.
A quadrilateral with one pair of parallel sides.
A quadrilateral with all sides of equal length, but not all angles of same measure.
A polygon with four sides.
A quadrilateral with two pairs of consecutive, equal sides.

TRIANGLE – 3 SIDES
SQUARE – 4 SIDES
PENTAGON – 5 SIDES
HEXAGON – 6 SIDES
HEPTAGON – 7 SIDES
OCTAGON – 8 SIDES
NONAGON – 9 SIDES

The hexagon – a shape with 6 sides – is one of the most common shapes in nature. From honeycombs to snowflakes and patterns found on fruit skins, the hexagon is present everywhere!
