Question

Which of the following is/ are two dimensional figures?
(a) Square
(b) Circle
(c) Cube
(d) Both A and B

Answer 1

Hint: In this question, we first need to know what is a two dimensional figure. A figure that has a length and a breadth is called a two dimensional figure .Then conclude the given options in the question accordingly to get the answer.

Complete step-by-step answer:
We see different shapes of objects around us everyday in various shapes and sizes. In general we usually see shapes like circles, triangles and squares.
In geometry, a shape or a figure that has a length and a breadth is called a two dimensional figure. In other words, a plane object that has only length and breadth is 2 dimensional.
Straight or curved lines make up the sides of these 2 dimensional figures. Also, these figures can have any number of sides.. In general, plane figures made up of lines are known as polygons.
Two dimensional figures do not have any thickness and can be measured in only two faces. Here, only x and y axes are used to represent them.
Examples of two dimensional figures: Triangle, Rectangle, Square, Circle etc.
In our day to day life, we see several other objects like books, ball, ice-cream cone etc around us in different shapes. The common thing in these objects is that they have length, breadth and also height or depth. Thus, they have three dimensions and are called three dimensional figures.
The figures which have length, breadth and height or depth are called three dimensional figures. Here, we need x, y and z axes to represent them.
Examples of three dimensional figures: Cube, Cylinder, Sphere, Cone etc

Here, the square has only length and breadth. So, it is a two dimensional figure.

Here, the circle has only radius. So, it is a two dimensional figure.

Here, the cube has length, breadth and height. So, it is a three dimensional figure.

Thus, the two dimensional figures in the given question are Square and Circle.
Hence, the correct option is (d).

Note:It is important to note that the circle can be represented on a paper and it has only radius and area. Thus, it is a two dimensional figure not three dimensional. Here, the square has length and breadth so it is also a two dimensional figure.It is also to be noted that the cube has length, breadth and height which in terms can also be viewed as our room. Thus, it is a three dimensional not two dimensional.
