Oval Shape

In this lesson, we will explore our understanding about shapes by learning about oval shape including its meaning, properties, construction, some solved examples and a few interactive questions for you to test your learning.

When we squeeze or compress a circle, we get an oval shape.

In the given simulation, drag the slider to see the formation of an oval. All these shapes you are getting are considered oval.

Lesson Plan

What Is an Oval Shape?

A 2D closed figure that looks like an egg is called an oval. 

Oval shape

The term "oval" is taken from the latin word "ovum," which means egg. 

There is no defined shape for an oval in math, but it is easy to differentiate an oval from a given set of figures based on its properties. 

Let us learn about the properties of an oval shape in the next section.

 
Thinking out of the box
Think Tank
  1. Do you ever wonder why eggs are oval in shape?

 The oval shape of eggs provides them strength so that they don't crack when the mother bird sits on them. Also, because eggs are oval in shape and not circular, they do not roll and fall from the nest easily.

What Are the Properties of an Oval Shape?

  1. An oval has no straight sides.
  2. It has no corners.
  3. It has one flat face.
  4. In some cases, a line of symmetry can be observed.
  5. In case of an oval, there is no fixed distance from the center point to the circumference

important notes to remember
Important Notes
  1. Both circle and oval are categories or types of ellipse.
  2. Oval in a three-dimensional plane is known as ovoid.

How to Contruct an Oval Shape?

There are two ways to make an oval shape. First is to simply draw it without the use of compass and second is to construct it with the help of a ruler and compass.

  1. Without the use of compass

Step 1 - Take 2 nails, a pencil, and a rubberband.

Step 2 - Place the tip of two nails on two opposite sides of the rubberband and attach it properly in a straight line on a piece of paper. 

Step 3 - Use the third pencil and draw an oval by stretching the rubberband.

       2. With the use of compass

Step 1- Using a compass, construct two circles touching each other.

Step 2- Join the center point of both the circles by drawing a straight line.

Step 3- Construct a perpendicular bisector of the line by expanding the legs of compass upto the diameter of any one circle.

Step 4- Expand the legs of the compass as equal to the addition of the distances of diameter of one circle and radius of another circle, and draw lines keeping the tip of the compass on each of the arc one by one.

Construction of an oval

Example

Now let us look at the given simulation to deepen our understanding about construction of oval shape.


Solved Examples

Example 1

 

 

Given below is the image of a mirror. What is shape of the mirror? How many faces are there in the given image? 

Oval shape real-life examples

Solution

This mirror is oval in shape. There is only one face in the figure.

Oval shape; one face
Example 2

 

 

A teacher placed certain items in front of her students and ask them to select oval-shaped items from the given list.

Select oval-shaped objects

Solution

Shape of clock- Oval

Shape of basketball- Circle

Shape of football- Oval

Shape of floor mat-  Oval 

Shape of table- Rectangle

\(\therefore\) Clock, football, and floor mat are oval in shape.

Frequently Asked Questions(FAQs)

1.Can an oval be round?

Yes. An oval that approaches a circle will be considered as round in shape.

2.Are circle and oval the same?

No. A circle can be considered as an oval, but an oval may not be a circle because it does not have a common distance from the center (radius).

3.Is oval a 2D shape?

Yes, oval is a 2D Shape. A similar figure in 3D is known as ovoid.
