a. 90 - degree angle
b. 70 - degree angle
c. 50 - degree angle
d. 45 - degree angle

1. to check level conditions over a significant distance, such as a building foundation or long surface, the best level to use is a

a. torpedo level
b. laser level
c. digital level
d. spirit level

1. which of the following saws would likely have the fewest teeth per inch, resulting in a coarser cut?

a. a hacksaw
b. a coping saw
c. a ripsaw
d. a crosscut saw

1. the saw shown in the figure above is called a

a. keyhole saw
b. drywall saw
c. coping saw
d. hacksaw

1. the best designed saw for cutting miter joints is a

a. handsaw
b. backsaw

d. hacksaw

1. when using a utility knife, place a piece of scrap material under the object you are cutting to

a. see the object more clearly
b. keep the blade sharp
c. protect the surface under the object
d. avoid electrocution

Explanation:

1. Spirit levels can often check 45 - degree angles in addition to level and plumb.
2. Laser levels are best for checking level conditions over long distances due to their ability to project a straight - line over far ranges.
3. Ripsaws typically have fewer teeth per inch as they are designed for cutting with the grain.
4. Without the figure, we assume based on general knowledge. A keyhole saw is used for cutting holes in materials like drywall.
5. Backsaws are well - designed for making precise cuts like miter joints.
6. Placing scrap material under the object when using a utility knife protects the surface beneath the object being cut.

Answer:

1. d. 45 - degree angle
2. b. laser level
3. c. A ripsaw
4. a. keyhole saw
5. b. backsaw
6. c. protect the surface under the object
