Explanation

We are given two sets:

- A = {1, 2, 3}  

- B = {2, 3, 4, 5}

Intersection (A ∩ B) means finding the common elements that are present in both sets A and B.

Now compare the elements:

- A contains: 1, 2, 3  

- B contains: 2, 3, 4, 5

The common elements are: 2 and 3

Explanation

Laser yards or laser levels are tools used in construction and surveying to ensure surfaces are level or properly aligned.

Applications:  

   - Construction (walls, floors, ceilings)  

   - Surveying (land measurements)  

   - Interior Work (tile, cabinetry, wallpaper)

Saves Time & Increases Accuracy:  

   More precise than manual tools like spirit levels or chalk lines.

 Types:  

   - Rotary laser for 360° coverage  

   - Line laser for straight lines  

   - Dot laser for pinpoint accuracy
