Answer Expert Verified Answer: for this you will simply have to use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.

## Why do we only use a compass and straightedge when doing geometric constructions?

The compass and straightedge is more important in constructing geometric structures than other drawing tools such as rulers and protractors. Because steps taken with a compass and straightedge cannot be seen at first glance and this situation become a problem for students.

## What are the steps for using a compass and straightedge to construct a line through point A?

- Answer:
- Step 1 : Use the straightedge to draw a line n that passes through P and intersect line m, lebel the point of intersection as X,
- Step 2 : Place the point of the compass on point X and draw an arc that intersect line m and n, label the intersection point A and B,

## What are the steps to construct parallel lines?

How to Construct Two Parallel Lines

- The first thing you do is draw a straight line. It can be any length.
- Step 2: Steps Two & Three. Place the stylus of the compass on the point, and swing the compass down to make two marks on the line.
- Step 3: Step Four & Five.
- Connect these 3 points, and now you have 2 parallel lines!

## When constructing parallel lines with a compass and straightedge how should you start the construction 5 points?

When constructing parallel lines with a compass and straightedge, how should you start the construction? Measure the length of the original line and make an arc. Create a line that intersects the given line with your straightedge. Open the compass to the width of the line and draw two arcs.

## How do you calculate representative factor?

Explanation: Representative factor is the ratio of the length represented in drawing to the actual length. Here given actual length is 1 m =100cm and length of drawing is 5 cm. R.F. =5 cm/100 cm = 0.05 (or) = 1/20.

## What is double stroke lettering?

Double Stroke Lettering: In Double Stroke Lettering the line width is greater than that of Single Stroke Lettering. Double Stroke Lettering is further divided into: a) Double Stroke Vertical Gothic Lettering. b) Double Stroke Inclined Gothic Lettering. A stencil is mostly used when hand drawing double stroked letters.

## What is the difference between single stroke and double stroke letters?

Double Stroke Lettering In Double Stroke Lettering the line width is greater than that of Single Stroke Lettering. Use one stroke per line. • Horizontal Stroke are drawn left to right.

## What is the purpose of lettering in drawing?

It is used to describe, or provide detailed specifications for, an object. With the goals of legibility and uniformity, styles are standardized and lettering ability has little relationship to normal writing ability. Engineering drawings use a Gothic sans-serif script, formed by a series of short strokes.

## What is the importance of lettering?

PERSONALITY BEHIND WORDS They are there merely to communicate information. Through hand-lettering however, we are able to put meaning into a design. Lettering a word can make it vibrant, quiet, serious, or fun. This is what makes lettering so powerful: we can put personality and voice into an otherwise toneless word.

## What are the qualities of lettering?

The effective letter is one which possesses following qualities:

- Clearness. The effort of letter writing is meaningless if the matter of the letter is not clear to the reader.
- Correctness. The clearness of the letter depends on its correctness.
- Completeness.
- Conciseness.
- Attractiveness.
- Coherence.
- Courtesy.
- Creativeness.
