What is the definition of parallel lines?
Parallel lines are two lines that are always the same distance apart and never touch. In order for two lines to be parallel, they must be drawn in the same plane, a perfectly flat surface like a wall or sheet of paper. Any line that has the same slope as the original will never intersect with it.

What is a parallel bar in drafting?
When you want to draw a line that is square with your drawing paper, or use drafting triangles on, a parallel straightedge bar will perform the job with ease. Parallel straightedge bars are great for making quick sketches before reproducing your ideas in cad.
2
Do parallel lines have to have the same slope?
The slopes of the lines are the same and they have different y-intercepts, so they are not the same line and they are parallel. Two non-vertical lines are perpendicular if the slope of one is the negative reciprocal of the slope of the other.
3
How many sets of perpendicular lines are in a rectangle?
Rectangles also have right angles. Again, let's look at the rectangle on our screen. Like a square, a rectangle has lines that are perpendicular to two other lines. This means it also has four right angles.
4
What is a skew line?
In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron.

What does it mean to be parallel in English?
Parallel structure means using the same pattern of words to show that two or more ideas have the same level of importance. This can happen at the word, phrase, or clause level. The usual way to join parallel structures is with the use of coordinating conjunctions such as "and" or "or."

How do you find a perpendicular line?
First, put the equation of the line given into slope-intercept form by solving for y. You get y = 2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.

What are two lines that intersect?
Two lines that intersect and form right angles are called perpendicular lines. The symbol ⊥ is used to denote perpendicular lines. In Figure , line l ⊥ line m.

What is a parallel line?
Parallel lines are two lines that are always the same distance apart and never touch. In order for two lines to be parallel, they must be drawn in the same plane, a perfectly flat surface like a wall or sheet of paper. Any line that has the same slope as the original will never intersect with it.

Which is the definition of a line segment?
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.

What does a parallel lines look like?
Examples of parallel lines are all around us, in the two sides of this page and in the shelves of a bookcase. When you see lines or structures that seem to run in the same direction, never cross one another, and are always the same distance apart, there's a good chance that they are parallel.
11
What is a transversal line?
In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points. Transversals play a role in establishing whether two other lines in the Euclidean plane are parallel.
12
Is parallel to symbol?
Symbol. The parallel symbol is . For example, indicates that line AB is parallel to line CD. In the Unicode character set, the "parallel" and "not parallel" signs have codepoints U+2225 (∥) and U+2226 (∦), respectively.
13
What is the horizontal line?
In geometry, a horizontal line is one which runs from left to right across the page. It comes from the word 'horizon', in the sense that horizontal lines are parallel to the horizon. The horizon is horizontal. Its cousin is the vertical line which runs up and down the page.
14
How do you find the slope of a perpendicular line?
To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = –10 is m = 4/5. Therefore, the slope of the line perpendicular to this line would have to be m = –5/4. Step 2: Use the slope to find the y-intercept.
15
What is the perpendicular bisector of a line?
A perpendicular bisector of a line segment is a line segment perpendicular to and passing through the midpoint of (left figure). The perpendicular bisector of a line segment can be constructed using a compass by drawing circles centered at and with radius and connecting their two intersections.
16
What is the definition of a bisector?
A bisector is something that cuts an object into two equal parts. It is applied to angles and line segments. In verb form, we say that it bisects the other object.
17
What is a shape with parallel sides?
The trapezoid has one pair of parallel sides. The parallelogram, rectangle, and square all have two pairs of parallel sides. Other less common shapes with parallel sides include any of the '-gons' with an even number of sides, such as a hexagon, octagon, decagon, etc.

What is the significance of the 49th parallel?
This one divides Blaine, Washington from Surrey, British Columbia. The 49th parallel north as a border between the Canadian provinces of British Columbia, Alberta, Saskatchewan and Manitoba (to the north), and the U.S. states of Washington, Idaho, Montana, North Dakota and Minnesota (to the south).

What is a parallel circuit?
A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. Each load connected in a separate path receives the full circuit voltage, and the total circuit current is equal to the sum of the individual branch currents.
