# Two Dimensional Shapes || Grade 1 Math

In this post we will learn about important two dimensional shapes like circle, square, rectangle etc.

First we will understand the basic dimension and property of the shapes.

After that we will solve some worksheets which is as per the standard of Grade 1 Math curriculum.

## What are shapes?

Shapes are basically outer boundary of any objects.

There are various shapes like rectangle, circle, square, etc. which look different to each other.

Let us learn some of the important shapes.
Please note that all the below shapes are also known as Polygons.

### Shape of Triangle

Its a shape with 3 sides.

You can see triangle shape in various objects of daily life.
Below you can see Watermelon slice, Pizza slice and Traffic signs, all are triangle in shape.

### Shape of Square

It’s a shape with 4 sides.
All sides are equal in length

In the real life you will find many square shapes.
Below given objects like Dice, Chessboard and Clock are square in shape

### Shape of Rectangle

Its a shape with 4 side.
In Rectangle, opposing sides are equal

Below is the image of rectangle
Here, side 1 is equal to side 3
and, side 2 is equal to side 4

Some of the real examples of rectangular shapes are chalkboard, television and notebook

### Shape of Rhombus

Its a shape having 4 sides with all sides equal to each other.

Rhombus is different from square as in rhombus the angle between sides can be be different than 90 degree.

Rhombus basically looks like a shape of diamond.

Some of the example of rhombus are Kites, Diamonds etc..

### Shape of Pentagon

Its a shape with 5 sides

### Shape of Hexagon

Its a shape with 6 sides

### Shape of Circle

Its a shape with no sides.

You can see the above figure, it has no sides.

Some of the objects in the form of circle is given below:
