**Title: Understanding Circle Geometry: The Intersection of Lines and Circles**

**Introduction**

In this exercise, we explore a geometric problem involving a circle and intersecting lines. The question aims to find the length of a specific line segment within the geometric figure provided.

**Geometric Problem Description**

The figure shows a circle intersected by two lines forming a triangle and a segment inside the circle. Here is the detailed explanation of the components:

1. **Points and Line Segments**:
   - Point \( R \) is outside the circle.
   - Line segment \( RP \) passes through the circle intersecting it at points \( Q \) and \( S \).
   - Point \( Q \) lies on the circumference of the circle and \( P \) is another point on the circumference on the right side.
   - Point \( S \) is on the circumference on the lower left side.
   - The triangle formed has vertices \( R, Q, \) and \( S \).

2. **Distances**:
   - \( RQ = 24 \) units.
   - \( RS = 36 \) units.

**Question**
- The task is to find the length of segment \( PQ \).

**Explanation of Diagram**

The diagram illustrates the setup:
- The circle is centered on the diagram, with a curved line representing its circumference.
- \( RQ \) and \( RS \) are straight lines extending from point \( R \) to points \( Q \) and \( S \) respectively.
- \( Q \) and \( P \) are points on the circle where line segment \( PQ \) resides.
- \( Q \) is positioned to the top-left within the circle, while \( P \) is to the right.

Given the triangle \( RQS \), with side lengths \( RQ = 24 \) and \( RS = 36 \), and knowing these segments extend through the circle intersecting it, a variety of geometric methods can be employed to determine \( PQ \). The solution might involve leveraging properties of similar triangles, the power of a point theorem, or other geometric and algebraic techniques.

**Conclusion**

The given geometric figure offers valuable practice for students understanding the intersection of lines with circles and the relationships within. Calculating the length of segment \( PQ \) entails analyzing the structure, applying geometric principles, and solving algebraically to find the missing length.
