### These are used to project lines from a horizontal base, project isometric drawing as well as lines in an oblique drawing.

Explanation
Triangles are commonly used in drafting and engineering to project lines from a horizontal base. The three sides of a triangle provide stability and accuracy when creating projections. Triangles are also useful for creating isometric drawings, which show a three-dimensional object in a two-dimensional space. Additionally, triangles can be used to project lines in oblique drawings, which depict objects at an angle. The angles and sides of a triangle allow for precise measurements and angles in these types of drawings.

### This is usually used in order to draw some irregular shapes or curve.

Explanation
A French curve is a drawing tool that is commonly used to create irregular shapes or curves. It is designed with a variety of curved edges that can be used to trace or draw smooth, flowing lines. The tool is particularly useful in design, architecture, and engineering, where precise and intricate curves are needed. By placing the French curve on a surface and tracing along its edges, one can easily create complex curves that would be difficult to draw freehand.

### This instrument is used to draw circles as well as arcs.

Explanation
A compass is a tool used for drawing circles and arcs. It consists of two legs, one with a sharp point and the other with a pencil or pen attached. The sharp point is placed at the center of the desired circle or arc, while the pencil or pen is used to trace the shape as the compass is rotated. This tool is commonly used in geometry, drafting, and technical drawing to create precise and accurate circular shapes.

### This is used to layout measurements at reduced or enlarge sizes.

Explanation
A triangular scale is a tool used in technical drawing and drafting to layout measurements at reduced or enlarged sizes. It consists of a triangular-shaped ruler with different scales on each of its three sides. By using the appropriate scale, measurements can be accurately and proportionally represented on a drawing or plan. This tool is commonly used in fields such as architecture, engineering, and design to ensure accurate scaling of measurements.

### These are used to transfer distance or measurements.

Explanation
Dividers are commonly used to transfer distances or measurements accurately. They consist of two pointed legs joined at a pivot point, allowing them to be adjusted and locked in place. By placing one leg at a starting point and using the other leg to mark a desired distance, dividers can be used to transfer that measurement to another location. This makes them a useful tool in various fields such as engineering, woodworking, and drafting, where precision and accuracy are essential.

### ALPHABET OF LINES:Used to locate the center of features and represents axes of symmetry.

Explanation
The correct answer is "center line, center lines." In engineering and drafting, the alphabet of lines is a set of standard line types used to represent different features on a drawing. The center line is one of these line types and is used to locate the center of features and represent axes of symmetry. It helps in accurately positioning and aligning objects or components in a design. The plural form "center lines" is also mentioned in the answer, indicating that multiple center lines can be used in a drawing depending on the number of features or axes of symmetry present.

• 13.

### ALPHABET OF LINES.Used to indicate repeated details in an object.

Explanation
Phantom lines are used to indicate repeated details in an object. They are typically represented by a series of short dashes and long gaps. These lines help to show hidden or obscured features of an object, such as interior components or alternate positions. By using phantom lines, designers and engineers can provide a clearer representation of the object and convey important information about its structure or functionality.

• 14.

### ALPHABET OF LINES.Used to indicate where an imaginary cut is made through the object.

Explanation
The term "cutting plane line" refers to a line that is used to show where an imaginary cut is made through an object. The plural form of this term is "cutting plane lines". "Cutting plane" is a shortened form of the term, but it still refers to the same concept. Therefore, all three options - "cutting plane line", "cutting plane lines", and "cutting plane" - accurately describe the lines used to indicate the imaginary cut in an object.

Rate this question:

• 15.

### ALPHABET OF LINES.Used to show areas that have been cut.

Explanation
The correct answer is "section lines" because in the context of the given information, it is used to represent areas that have been cut. The plural form "section lines" implies that there are multiple lines used to indicate the cut areas, while the singular form "section line" suggests a single line.

Rate this question:

• 16.

### ALPHABET OF LINES.A type of break line that is used to separate internal and external features with broken out sections.

Explanation
The correct answer is "short break line, short break lines, short." A short break line is a type of break line that is used to separate internal and external features with broken out sections. It is used to indicate that a portion of the object has been removed for clarity or to show hidden details. The plural form "short break lines" is also correct as it refers to multiple instances of these break lines. "Short" alone is not a complete answer as it does not specify the type of break line being referred to.

### Label the dimension features.NUMBER 1.

Explanation
The dimension features.NUMBER 1 can be labeled as "feature size" because it refers to the size of a specific feature. Additionally, it can also be referred to as "size" since it represents the measurement or dimension of the feature. "Unit" is another suitable label as it indicates the specific unit of measurement used for the feature size. Similarly, "measurement" and "measurements" can be used as labels since they emphasize the act of measuring the feature size. Lastly, "units" can be used as a label to represent the different units in which the feature size can be measured.

### Label the dimension features.​NUMBER 2.

Explanation
The correct answer is to label the dimension features as arrowheads, arrowhead, arrow, and arrows. This means that these terms are used to describe different aspects or variations of the dimension features. "Arrowheads" refers to multiple instances of the feature, "arrowhead" refers to a single instance, "arrow" is a more general term for the feature, and "arrows" refers to multiple instances as well.

Rate this question:

• 29.

### Label the dimension features.​NUMBER 3.

Explanation
The correct answer is "dimension line, dimension lines." In technical drawings, dimension lines are used to indicate the size and location of features. They are typically represented as straight lines with arrows at each end. The plural form "dimension lines" is also correct because there may be multiple lines used to indicate different dimensions in a drawing.

Rate this question:

• 30.

### Label the dimension features.​NUMBER 4

Explanation
The correct answer is "extension lines, extension line". In technical drawing, extension lines are used to extend a line or edge beyond its natural termination point. They are typically thin and dashed lines that indicate the imaginary extension of a feature. An extension line is a single line used to extend a dimension line past the object being measured. Therefore, in this question, the correct answer is to label the dimension features as "extension lines" and "extension line".

Rate this question:

• 31.

### Label the dimension features.​NUMBER 5

Explanation
The correct answer is "visible gap, gap, space, visible space". This answer correctly labels the dimension features mentioned in the question. The term "visible gap" refers to a gap that can be seen or observed. "Gap" refers to a space or opening between two objects. "Space" is a general term for an area or volume. "Visible space" refers to an area or volume that is visible or can be seen.
