Introduction

In geometry, constructing regular polygons is an essential skill that requires precision and attention to detail. In this article, we will focus on constructing a regular hexagon and a regular octagon within a square. We will provide a step-by-step guide on how to construct these polygons using a ruler and a compass.

Constructing a Regular Hexagon

A regular hexagon is a six-sided polygon with all sides and angles equal. To construct a regular hexagon with each side measuring 45 mm, follow these steps:

Step 1: Draw a Circle

Draw a circle with a radius of 45 mm. This circle will serve as the base for our hexagon.

Step 2: Draw Six Radii

Draw six radii from the center of the circle to the circumference, each one 60 degrees apart. These radii will help us create the vertices of the hexagon.

Step 3: Draw the Sides of the Hexagon

Connect the vertices of the hexagon by drawing six sides, each one 45 mm long. Make sure to keep the sides straight and equal in length.

Step 4: Check the Hexagon

Verify that the hexagon is regular by checking that all sides and angles are equal.

Constructing a Square with a Regular Octagon

A regular octagon is an eight-sided polygon with all sides and angles equal. To construct a regular octagon within a square with each side measuring 100 mm, follow these steps:

Step 1: Draw a Square

Draw a square with each side measuring 100 mm. This square will serve as the base for our octagon.

Step 2: Draw Four Alternate Sides of the Octagon

Draw four alternate sides of the octagon, each one 100 mm long, within the square. These sides will help us create the vertices of the octagon.

Step 3: Draw the Remaining Sides of the Octagon

Draw the remaining four sides of the octagon, each one 100 mm long, to complete the octagon.

Step 4: Check the Octagon

Verify that the octagon is regular by checking that all sides and angles are equal.
