## What is the difference between constructing perpendicular lines?

Explanation: When there are two parallel lines, these two lines are never able to intersect or touch. … Perpendicular lines are two lines in which one of the lines intersects the other line, and the angles created from the intersection of these two lines are all right angles.

## Which mode allows users to draw 90 degrees straight lines?

90° straight lines can be drawn by switching the Ortho Mode to ON. or by pressing Function key (F8). Ortho mode is used.

## Is 300 degree the same as degrees in a drawing?

No. Inside a circle, where the lines are drawn inside a 300 degrees angle will correspond with a 60 degrees angle, but the shaded parts are different.

## Can you have curved parallel lines?

Curves can also be parallel when they keep the same distance apart (called “equidistant”), like railroad tracks.

## What is the rule for perpendicular lines?

Two lines are perpendicular if and only if the product of their slopes is . In other words, the slope of a line that is perpendicular to a given line is the negative reciprocal of that slope. Thus, for a line with a given slope of 3, the line perpendicular to that slope must be the negative reciprocal of 3, or .

## How do you describe parallel lines?

Parallel Lines: Definition: We say that two lines (on the same plane) are parallel to each other if they never intersect each other, ragardless of how far they are extended on either side. … Corresponding Angles are angles that are on the same side of the transversal and on the same side of each intersected line.
