Answer:
Matching the steps to the construction:
1. Step 1: Place the compass point on P, make an arc that crosses the given line twice. Name those intersections X and Y. → **2.**
2. Step 2: Change the compass setting to a larger radius. → **5.**
3. Step 3: Place the compass point at X. Make an arc above point P. → **4.**
4. Step 4: Keep the same compass setting. Place the point on Y and make an arc above point P. Name the intersection Z. → **3.**
5. Step 5: Use the straightedge to connect P and Z. → **1.**
So, the correct match is: 2-5, 5-1, 4-3.
