State the purpose of an Engineer's square, Straight edge, and match terms like Vernier Caliper, Allen keys, Spanner, etc., to their descriptions.

here's the solution for Question 1:

QUESTION 1

1.1 State the purpose or function of each of the following measuring instruments:

1.1.1 Engineer's square
The purpose of an Engineer's square is to $\boxed{\text{check and mark right angles (90 degrees) and to verify the flatness of surfaces}}$.

1.1.2 Straight edge
The purpose of a Straight edge is to $\boxed{\text{check the straightness of a surface or to draw straight lines}}$.

1.2 Choose a description from COLUMN B that matches a term in COLUMN A. Write only the letter (A-I) next to the question number (1.2.1-1.2.10).

Note: There are 10 terms in Column A and 8 descriptions in Column B. Therefore, two terms from Column A will not have a direct match.

• 1.2.1 Vernier Caliper: No direct match in Column B.
• 1.2.2 Allen keys: $\boxed{\text{B}}$
• 1.2.3 Spanner: $\boxed{\text{D}}$
• 1.2.4 Compressor: $\boxed{\text{C}}$
• 1.2.5 Dot punch: $\boxed{\text{G}}$
• 1.2.6 Screw thread gauge: No direct match in Column B.
• 1.2.7 Hydraulic jack: $\boxed{\text{H}}$
• 1.2.8 Rachet: $\boxed{\text{F}}$
• 1.2.9 Pipe wrench: $\boxed{\text{A}}$
• 1.2.10 Luminous intensity: $\boxed{\text{E}}$
