## What Is an Oval Shape in Math?

**An oval shape is a closed shape. It is a completely curved geometric figure.** Thus, it has no straight lines or vertices. It looks like a stretched-out, elongated, or a squashed circle. The shape is very similar to the shape of an ellipse. However, they are not the same.

Ovals are not precisely defined geometrical figures with strict mathematical properties. The term “oval” is a broad and informal term used to describe any elongated closed curve that is not circular but resembles a squashed circle.

The word “oval” is originated from the Latin word “*ovum*,” which means “an egg.’’ If you draw an outline of an egg, it will be oval in shape.

The oval shape is not particularly defined in geometry. We however use it to express the shape of egg-like objects.

## Properties of an Oval Shape

- It has no edges.
- It has no vertices.
- It is a 2D curved geometrical figure.
- It has only one flat face.
- It is a simple curve. It means that it does not overlap or self-intersect.
- It is convex. It means its surface is curved or rounded outward.
- In some oval shapes, a line of symmetry is present.

## Construction of an Oval Shape

As mentioned earlier, if we trace an egg on a piece of paper, we will get an oval shape. Let’s learn some other interesting ways to draw this curved shape.

The construction of an oval shape can be done in many ways. The first can be to simply draw it using a rubber band. Alternatively, we can construct it using a ruler and a compass.

**Construction of an Oval Shape Using a Rubber Band (Bold)**

To make an oval shape using a rubber band, follow the given steps:

**Step 1: **Take a rubber band, a pencil, and two nails.

**Step 2: **Fix the nails away from each other. The distance should be such that once the rubber bank is fixed on them, it makes a straight line. In other words, there should be some tension once we stretch the rubber band.

**Step 3:** Place the pencil inside the rubberband and draw an oval shape by stretching it while the nails keep the band in position.

**Construction of an Oval Shape Using a Compass**

To construct an oval using a compass, follow the steps given below:

**Step 1:** Construct two circles of the same radius that touch each other at one point. Let the centers be Q and S.

**Step 2: **Draw a straight line joining the center of both circles.

**Step 3:** Set the compass distance equal to the diameter. Keep the compass on Q and make arcs above and below. Repeat the same by keeping the compass at S.

Let the arcs intersect at points A and B.

**Step 4: **Set the compass distance equal to PS.** **With this distance and by keeping the needle at A, draw the lower half of the oval. Draw the upper half of the oval by keeping the compass at B.

**Construction of an Oval Shape Using Plus (+) Sign, Rectangle, or Circle**

Simply draw a plus sign (+), but draw the vertical line a bit longer. Now you can draw a curved shape that touches the endpoints of the two lines of the sign. Similarly, you can draw an oval using a rectangle or a circle.

## Oval Shape Around Us

Look around! Can you identify some oval shape objects? Take a look at a few examples of an oval shape.

## Oval vs. Circle

A circle is a 2D closed shape, such that all points on its boundary are equidistant from the center. Thus, the circle is a symmetric shape. An oval, on the other hand, is also a closed curve that has a stretched or elongated circular form. Unlike a circle, an oval shape lacks a constant distance from the center point to the boundary.

## Facts about the Oval Shape

- An oval is a closed curve resembling a squashed circle.
- Ovals usually possess an axis of symmetry, dividing them into mirror-image halves, but not all ovals have this property. Some ovals exhibit a line of symmetry, while others may have irregular or asymmetric outlines.
- The three-dimensional version of an oval is called an ovoid.

## Conclusion

In this article, we explored the fascinating world of oval shapes, encompassing their unique characteristics and versatile appearances. Ovals are not precisely defined geometrical figures. To enhance our understanding, let’s solve examples and attempt MCQs for better comprehension.

## Frequently Asked Questions about the Oval Shape

**What is the difference between an oval and a circle?**

A circle is a symmetric shape that is formed by a set of points, which are at a fixed distance from the center. An oval looks like an outline of an egg or a squashed circle. Ovals can vary in proportions, with some being more elongated than others. However, all circles are similar.

**What is a 3D oval called?**

A 3D version of an oval is called an ovoid.

**What is an ellipse? How is it similar to an oval?**

Every ellipse is an oval but not every oval is an ellipse. The ellipse has a balanced and uniform look. Ovals do not have foci defined, whereas ellipses have two focal points, which are important in defining the shape. An ellipse is a well-defined geometric figure.

**Are ovals round?**

The term “round” is used to describe circular objects. However, it is not a strict word since people commonly and loosely refer to oval shapes as round shapes.

**What are some types of ovals?**

Every ellipse is an oval. However, not every oval is an ellipse. We can draw many types of oval shapes since its perimeter doesn’t have to be of fixed size.
