**Title: Understanding Size Transformations: A Step-by-Step Guide**

**Description:**

This educational module explains how to perform a size transformation centered at a point O on a line m, taking a point P onto P′. The key steps involved are determining the center O and the transformed point Q′ for a point Q that lies on line m.

**Instructions:**

1. **Objective:** Explain how to draw:
   - (a) The center O of the transformation.
   - (b) The image Q′ of point Q, where Q lies on line m.

2. **Diagram Explanation:**
   - The diagram shows point P on line m, being transformed to P′. A line m is indicated, passing through point Q.

3. **Options for Explanation:**

   - **A.** The line PP′ passes through O, so constructing this line, along with line m, determines point O. \( \overline{PQ} \) and \( \overline{P'Q'} \) are parallel, so the line through P′ that is parallel to \( \overline{PQ} \) will meet line m at the desired point Q′.

   - **B.** \( \overline{PQ} \) and \( \overline{P'O} \) are parallel, so the line through P′ that is parallel to \( \overline{PQ} \) will determine O. The line PP′ passes through Q′, so constructing this line determines point Q′.

   - **C.** The line PP′ passes through O, so constructing this line determines point O. The line OQ passes through Q′, so constructing this line determines the point Q′.

   - **D.** \( \overline{PQ} \) and \( \overline{P'O} \) are parallel, so the line through P′ that is parallel to \( \overline{PQ} \) will determine O. The line OQ passes through Q′, so constructing this line determines the point Q′.

**Conclusion:**

Using the above methods, learners can understand how to perform a size transformation by accurately determining the center and transformed points on a given line. This exercise aids in grasping fundamental concepts of geometry transformations.
