On the perpendicular bisector of, the perpendicular bisector of AB

I've made a perpendicular bisector for segment AB.

Let's prove that it has to sit on the perpendicular bisector

We're asked to construct a perpendicular bisector of the line segment AB.

This line is a perpendicular bisector of AB, and so we have two right triangles

So to prove that C lies on the perpendicular bisector, we really have to show that CM is a segment on the perpendicular bisector, and the way we've constructed it, it is already perpendicular, we really just have to show that it bisects AB

and actually it will be a perpendicular bisector of the segment formed by those two points.

And now, this gives me two points that I can actually use to draw my perpendicular bisector.

Angle Bisector

Perpendicular

We know that this diagonal line over here is a perpendicular bisector so the height is just the distance from BE

Construct Bisector of This Angle

The bisector of an angle

So it, it will be both perpendicular and it will split the segment in two, so thus we can call that line L, that's going to be a perpendicular, it's a perpendicular bisector, so it's gonna be, it'll intersect in a 90 degree angle and it bisects it

Let's start off with segment AB, so that's point A, this is point B right over here, and lets set up a perpendicular bisector of this segment

What is the first step in constructing the angle bisector of angle A? what is the first step constructing angle bisector

Construct a line perpendicular to this line

Construct a perpendicular line through this point

Everything is nice and fine and perpendicular.

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

Select the angle you want to construct the bisector of...

This arbitrary point C that sits on the perpendicular bisector of AB, is equidistant from both A and B, and I could've known that if I drew my C over here, or here,

Select a line perpendicular to the new line...

They should all be perpendicular to your column.

Where do we put these new perpendicular lines?

But they do care about it being perpendicular.

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

PROBLEM Construct a line perpendicular to the given line.

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

Now we're gonna prove that AC is perpendicular to BD

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

And that line is going to be perpendicular to our original line.

A two dimensional space is defined by two perpendicular lines, which describe a flat plane

Your choices are the transforms works only if the normal is perpendicular to the mirror.

So let's see, they say what is the first step in constructing the angle bisector of angle (a).

The spindle sweep measurement will show that the spindle axis is perpendicular to the table surface

Earth does not rotate its axis of rotation is not perpendicular to the plane of the orbit.

An altitude by definition is going to be perpendicular down here. Now, an isosceles triangle is perfectly symmetrical.

These sides are perpendicular, or the angle between them is 90 degrees, or it is a right angle.

I'm going to do a quick argument or proof, as to why the diagonals of a rhombus are perpendicular.

And then where they intersect, that would that would give you that would give you an indication of where the angle bisector is.

And a three dimensional space adds a third perpendicular line, which gives us height and the world we're familiar with.

If this plane is directly perpendicular to the axis of these and this is where the plane goes behind it.

We could drop a perpendicular here, and that, the length of this line right here, is going to be our height.

So the fact that it's perpendicular means that this line will make a 90 degree angle where it intersects with AB.
