# How to Obtain a Convex Disc?

## Introduction

A convex disc is a commonly used shape in various fields, such as mathematics, physics, and computer science. In this article, we will explore different methods and approaches to obtain a convex disc. From understanding the concept of convexity to practical applications, we will cover all the necessary subtopics to give you a comprehensive understanding of obtaining a convex disc.

## 1. Understanding Convexity

Convexity is a fundamental concept in geometry that refers to the property of a shape to have no indentations or “cave-like” regions. A convex shape is one where, for any two points within the shape, the line segment connecting them lies entirely within the shape. In the context of a disc, a convex disc is a disc that does not have any irregularities or holes in its boundary.

## 2. Properties of Convex Discs

Before delving into the methods of obtaining a convex disc, it is essential to understand the properties associated with it. Some key properties of convex discs include:

• Smooth and continuous boundary
• No indentations or holes
• Constant width throughout
• Symmetrical shape
• High structural stability

## 3. Construction Techniques

There are several construction techniques that can be employed to obtain a convex disc. Some common methods include:

1. Using a compass and ruler
2. Using computer-aided design (CAD) software
