Look at these two intersecting lines.

Let me draw another property of angles of intersecting lines.

So, the two lines that the transversals are intersecting must be parallel

So, the first thing we can think about these aren't just diagonals, these are lines that are intersecting parallel lines

Maybe they only intersect in one point two lines intersecting in only two points.

This is alternate interior angles are congruent when you have a transversal intersecting two parallel lines

The lines constructed through the intersections of two conics. This is also defined for non intersecting conics.

So, let's just continue these so it looks a little bit more like transversals intersecting parallel lines

So, we know that AB is parallel to CD by alternate interior angles of transversal intersecting parallel lines

'cause it really just comes out of alternate interior angles and corresponding angles of transversals intersecting parallel lines

ADB for the exact same reason, they are alternate interior angles of a transversal intersecting these two parallel lines

What we have proved is the general case because all I did here is I just did two general intersecting lines

And these lines right here, you can kind of view them as where this plane is intersecting with this not quadrant octant.

We're intersecting the graph twice.

You're intersecting the graph twice.

No mathematician can remember so unprecedented and spectacular a result parallel lines intersecting, with autonomy becoming (for the brief moment of the bailout at least) interdependence.

And this diagonal, depending on how you view it is intersecting two sets of parallel lines so you can also consider it to be a transversal

And then after that, the only other information where they definitely tell us that two lines are intersecting at right angles are Line AB and WX.

By intersecting photons with infrasound waves,

They're parallel and not intersecting at all.

They could be a cross, symbolizing religion, an add sign, symbolizing a mathematical concept, the letter T from the alphabet, or they could just be two lines intersecting.

In the circle below, AB and CD are chords intersecting at E.

But any time you draw a vertical line, you're only intersecting it once.

But we're really intersecting the p axis instead of the y axis there.

Actually, regardless of whether the lines are parallel, if I just take any line and I have something intersecting, if this angle is 50 and whatever this angle would be, they would have to add up to 180 degrees.

Block off all streets intersecting Connecticut Avenue on a line from Wisconsin to the park.

Each intersecting line of the cross shall be 1 centimetre in length and 1 millimetre thick.

And when I see the way they're intersecting in conditions like the three I've just described,

lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtenant.

And instead of intersecting in two places it only intersects right there at x equals negative five.
