Perpendicular

They're perpendicular.

It would be perpendicular.

And they are perpendicular.

And perpendicular line, just so you have a visualization for what for perpendicular lines look like, two lines are perpendicular if they intersect at right angles.

RP is perpendicular to TA.

DB is perpendicular to BC

I draw two perpendicular lines.

Looks like this is perpendicular

So let's say that this is the perpendicular bisector of that side, this is the perpendicular bisector of that side, and this is the perpendicular bisector of that side

This is neither parallel nor perpendicular.

So these two lines are perpendicular.

Well, this one has perpendicular diagonals.

Now let's think about perpendicular lines.

What they want us to prove is that their diagonals are perpendicular, that AC is perpendicular to BD

So you have parallel, you have perpendicular, and, of course, you have lines that are neither parallel nor perpendicular.

And it has to be perpendicular to one of the other lines, you can't be just perpendicular by yourself.

So the perpendicular line, and I won't review it here, but the perpendicular line has a negative inverse slope.

Construct a line perpendicular to this line

Construct a perpendicular line through this point

We are just assuming that it's perpendicular

So these two lines are definitely perpendicular.

Everything is nice and fine and perpendicular.

This side is perpendicular to the base.

that DB, if I call them, maybe the line segment DB is perpendicular, is perpendicular to line segment BC, or we could even say that ray BD, is instead of using the word perpendicular there is sometimes this symbol right here, which just shows two perpendicular lines,

Select a line perpendicular to the new line...

Where do we put these new perpendicular lines?

Scott is constructing a line perpendicular to line

So this XC is perpendicular to line L.

And so UV, ST they're perpendicular to CD.

It's a line that's perpendicular to this plane.

So this must be on the perpendicular bisector.

See how it rests perpendicular to the wall.

We're defining perpendicular to mean the theta between two vectors a and b are perpendicular if the angle between them is 90 degrees.

The perpendicular line through a given segment's mid point.

Then this orange line, that's perpendicular to the yellow

PROBLEM Construct a line perpendicular to the given line.

But its diagonals actually intersect at a perpendicular line.

We are asked which of these lines are perpendicular.

In the figure above XC is perpendicular to L.

So Line AB is definitely perpendicular to Line WX.

So it must also be on this perpendicular bisector

Now, the normal line slope is perpendicular to this.

I wanna prove that segment AB, segment AB is perpendicular

Well, we have a perpendicular here, you can imagine the
