So they say, each cross section perpendicular to the x axis is a square.

So it says for this solid, each cross section perpendicular to the x axis, right?

File Submarine cable cross section 3D plain.svg_right_thumb_300px_A cross section of a modern submarine communications cable.

Everything is in cross section.

Obviously, this is a cross section.

This is kind of a cross section.

This would be a cross section of it.

So I'm going to do a cross section.

And of course, this is a cross section.

Commissioners represented a broad cross section of the community.

Perpendicular

So we're still dealing with if we take a cross section, if we were to cut this figure this area would be the cross section.

They're perpendicular.

Imagine some device where this is kind of a cross section.

So let me draw a cross section of a cell membrane.

He said she was a cross section of the American public.

You're actually looking at the cross section of a memory right now.

So let me draw a cross section of the Earth over here.

We learned that the dot product of 2 vectors tells you how much 2 vectors move together, and the cross product tells you how much the perpendicular, it's kind of the multiplication of the perpendicular components of a vector.

Section modulus is a geometric property for a given cross section used in the design of beams or flexural members.

Besides, cross section regressions are fairly treacherous and can lead to misleading conclusions.

The mission met with a wide cross section of Burundian and international stakeholders.

It would be perpendicular.

And they are perpendicular.

Participants represented a broad cross section of nations with different cultures and legal systems.

Here's a cross section of one of the old trees that's been cut down.

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.

ABCL's strategy was to introduce products and services covering an entire cross section of India's entertainment industry.

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.
