1. What is the primary purpose of a framing square in carpentry?
A. Measuring weight of materials
B. Checking and marking right angles
C. Cutting wood
D. Sanding surfaces
Answer: B
The framing square is mainly used to establish and verify 90-degree
angles in layout work, especially in framing walls, roofs, and stairs. It
also assists in marking straight cuts and measuring rafters, but its core
function is ensuring accurate right angles in construction.
2. Which type of wood joint is commonly used for corner framing in
walls?
A. Dovetail joint
, B. Butt joint
C. Mortise and tenon
D. Lap joint
Answer: B
Butt joints are widely used in basic wall framing because they are

mortise and tenon are typically used in furniture or heavy timber
work.

A. Plumb bob
B. Chalk line
C. Spirit level

B. Ensuring corners are 45 degrees
C. Making corners exactly 90 degrees
D. Cutting wood diagonally
Answer: C
Squaring a layout refers to ensuring that corners form perfect right
angles, which is critical for structural integrity and proper fit of
building components.

A. Coping saw
B. Hacksaw
C. Circular saw
D. Keyhole saw
Answer: C
A circular saw is commonly used for straight cuts in framing lumber
because it is fast, powerful, and accurate when guided properly.
7. What is the function of a plumb bob?
A. Measuring length
B. Determining vertical alignment
C. Cutting angles
D. Sanding wood
Answer: B
A plumb bob uses gravity to establish a true vertical line, ensuring
walls and structures are perfectly upright.
