A line constructed through a point, perpendicular to another line or segment.

A line constructed through a point, and parallel to another line or segment

And it's a straight line.

Free hand Draw non linear lines

Line Draw a straight line vertically, horizontally or at 45 deg. angles

So here we have a line and a point outside the line.

There'll be two lines, like this.

The polar point of a line with respect to a conic.

Select the first of the two possibly orthogonal lines...

Select the other of the two possibly orthogonal lines...

I ask the question, how many lines can I draw through the point but never meet the original line?

Select the first of the two possibly parallel lines...

Select the other of the two possibly parallel lines...

There's a straight line, and there is an infinite number of lines that go through the point and never meet the original line.

Draw a straight line here.

Get back into one line, damn it.

Test whether two given lines are orthogonal

It literally flat lined.

These two lines cut across each other at right angles.

History is not linear.

Come on now, move it into line.

And I have a point outside the line. How many straight lines can I draw through the point but never meet the original line?

I have a straight line on my spherical surface.

Construct a line through this point

Before I talk about that, I've written down at the bottom there the slope of this curve, this straight line.

Let me draw a line there, so I have a right angle.

Test whether two given lines are parallel

Everything is nice and fine and perpendicular.

Construct a line perpendicular to this line

Select a line perpendicular to the new line...

The relation is, however, not a straight line.

So we ask the question again, How many straight lines can I draw through the point, but never meet the original line?

Construct a line parallel to this line

Select a line parallel to the new line...

And negative alpha is the slope of that line I showed you before.

Between Fujian and Taiwan, there are eight ocean passenger shipping routes, seven direct passenger air routes and four unfixed air routes. Of the passenger volumes of the ocean routes and air routes between Taiwan and the Mainland, the shares of Fujian Taiwan routes are over 98 and 10 , respectively.
