i am a bit confused with rhombus,trapesim and prism

Hello Aash

First of all you need to understand that Rhombus and trapezium are two dimensional objects(consisting of only two dimensions), i.e, we can draw these objects on a sheet of paper. On the other hand Prism is three Dimensional object(3-D) and its structure cannot be explained on paper.

RHOMBUS :-

Rhombus is a closed figure having 4 equal sides. This should not be mistaken as a square because there is a slight difference between two of them. In a square all angles are equal to 90 degree( right angles), but in a rhombus all angles are not equal to 90 degree

Here are some properties of rohmbus

• All 4 sides are equal
• Opposite sides are parallel to each other ( Parallel lines means lines that will never intersect)
• Opposite angles are equal to each other
• The sum of adjacent angles is 180 degree

TRAPEZIUM:-

Trapezium is also a closed figure having 4 equal sides, but in this case 1 pair of opposite sides are parallel to each other while the other pair of opposite sides are not parallel to each other.

Here are some properties of trapezium

• One pair of opposite sides are parallel
• Other pair of opposite side is not parallel

PRISM

Prism is a 3-D object formed by putting triangles and rectangles together. A triangular prism look like this:-



I hope that now you are clear with the concept and if you are satisfied with my answer and efforts please give a thumbs up!!!

 

good explanations

? ? ? ? ?PRISM

A solid object with two identical ends and flat sides:


? The sides are parallelograms (4-sided shape with opposites sides parallel)
? The cross section is the same all along its length

The shape of the ends give the prism a name, such as "triangular prism"

It is also a polyhedron. Rhombus?(Jump to Area of a?Rhombus?or Perimeter of a?Rhombus?) A?Rhombus?is a flat shape with 4 equal straight sides TRAPESIM Definition of?Trapezium?more ...

In plane Euclidean geometry, a rhombus is a simple quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.
Area: ½ x (product of the lengths of the diagonals)
Perimeter: 4 x side
Number of vertices: 4
Number of edges: 4
Properties: Isotoxal figure, Convex polygon
Type: Parallelogram, Quadrilateral, Kite
Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic, and fluorite. A dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow).
In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid in American and Canadian English but as a trapezium in English outside North America.
Area: ½ x (sum of the lengths of the parallel sides) x perpendicular distance between parallel sides
Perimeter: sum of lengths of sides of trapezoid
Number of vertices: 4
Number of edges: 4
Properties: Convex polygon
Type: Quadrilateral

very funny

same as somyaadipta

right! nice!

For prism

A Rhombus is a flat shape with 4 equal straight sides.

A rhombus looks like a diamond

	All sides have equal length
	Opposite sides are parallel, and opposite angles are equal (it is a Parallelogram).
	The altitude is the distance at right angles to two sides
	And the diagonals "p" and "q" of a rhombus bisect each other at right angles.

A trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel.

And a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides:

	Trapezoid	Trapezium
In the US:	a pair of parallel sides	NO parallel sides
In the UK:	NO parallel sides	a pair of parallel sides
(the US and UK definitions are swapped over!)

A solid (3-dimensional) object which has six faces that are rectangles.

It has the same cross-section along a length, which makes it a prism. 

It is also a "cuboid".

Thanksfor ask questions

This is called rhombus

This is prism

This is trapezium

Same to piyush

fnrues

Good explation

so what should we do

A solid object with two identical ends and flat sides:


? The sides are parallelograms (4-sided shape with opposites sides parallel)
? The cross section is the same all along its length

The shape of the ends give the prism a name, such as "triangular prism"

It is also a polyhedron. Rhombus?(Jump to Area of a?Rhombus?or Perimeter of a?Rhombus?) A?Rhombus?is a flat shape with 4 equal straight sides TRAPESIM Definition of?Trapezium?more ... A 4-sided flat shape with straight sides and NO parallel sides. (Called a trapezoid in the UK. Both US and UK definitions of?Trapezium?and trapezoid are swapped over.) See: Trapezoid
