here are the solutions to the questions: Question 1: Step 1: Understand the term "fillets". Fillets are rounded corners or edges. Step 2: Identify the instrument used to draw arcs of specific radii, which are essential for creating fillets. A radius template contains various curves of defined radii. The correct option is d. Question 2: Step 1: Observe the line type shown in Fig. 1. It is a long dash, short dash, long dash pattern. Step 2: Recall standard line types in technical drawing. This pattern is universally recognized as a centre line, used to indicate the axis of symmetry for cylindrical or symmetrical objects. The correct option is a. Question 3: Step 1: Understand the definition of a reference line for dimensioning. This is a fundamental concept in technical drawing. Step 2: Identify the term for a theoretically exact point, axis, or plane from which dimensions are established. This is known as a datum. The correct option is b.
