Introduction

In this article, we will delve into a geometric configuration involving a square inscribed in a circle, which is further inscribed in another square. The given diagram illustrates the setup, with the square ABCD containing the circle and the square registered in the circle. We will analyze the relationship between the squares and the circle to determine the measure of the side length of the smaller square.

The Geometric Configuration

The given diagram shows a square ABCD with a circle inscribed within it. Inside this circle, there is another square registered, denoted as EFGH. The side length of the larger square ABCD is given as 4m. Our objective is to find the measure of the side length of the smaller square EFGH.

Key Concepts and Principles

To solve this problem, we need to apply various geometric concepts and principles. The key concepts involved are:

Inscribed and Circumscribed Shapes: A shape is said to be inscribed in another shape if it lies entirely within the other shape. Conversely, a shape is said to be circumscribed around another shape if the other shape lies entirely within it.
Circle Properties: A circle is a set of all points in a plane that are equidistant from a central point called the center. The distance from the center to any point on the circle is called the radius.
Square Properties: A square is a quadrilateral with four equal sides and four right angles.

Analyzing the Geometric Configuration

Let's analyze the given geometric configuration step by step:

Circle Inscribed in Square ABCD: The circle is inscribed in the square ABCD, meaning that the diameter of the circle is equal to the side length of the square. Since the side length of the square ABCD is 4m, the diameter of the circle is also 4m.
Square EFGH Registered in Circle: The square EFGH is registered in the circle, meaning that the diagonal of the square EFGH is equal to the diameter of the circle. Since the diameter of the circle is 4m, the diagonal of the square EFGH is also 4m.
Relationship Between Squares: The diagonal of a square is equal to the side length multiplied by the square root of 2 (√2). Therefore, if the diagonal of the square EFGH is 4m, we can find the side length of the square EFGH using the formula:

Side Length = Diagonal / √2

Calculating the Side Length of Square EFGH

Now that we have established the relationship between the squares, we can calculate the side length of the square EFGH.

Side Length = Diagonal / √2 = 4m / √2 = 4m / 1.4142 ≈ 2.828m

Therefore, the measure of the side length of the smaller square EFGH is approximately 2.828m.

Conclusion

In this article, we analyzed a geometric configuration involving a square inscribed in a circle, which is further inscribed in another square. We applied various geometric concepts and principles to determine the measure of the side length of the smaller square EFGH. The key concepts involved were inscribed and circumscribed shapes, circle properties, and square properties. By understanding these concepts and applying them to the given geometric configuration, we were able to calculate the side length of the smaller square EFGH.
