>> This is an illustration of -- 2-2, the second part of lab 2.
I'm going to start by creating three circles.
The circle in the middle
with center zero comma 3.75 of radius 1.
And then another circle at center --
the coordinates of the center are 1.5 comma .75.
That's the lower right circle of radius .75.
And then the third circle, 2.5 comma 5.75 of radius 1 as well.
Then, next I'm going to do, is I'm going to create a --
I want to make sure that tangent is on but not perpendicular.
So I'm going to make a -- the line tangent to the circle
and tangent to the circle.
Line tangent to the circle.
And I want to make sure that perpendicular is on.
So I say perpendicular to the line.
That creates that short line tangent to the circle
and perpendicular to the line.
Next thing I'm going to do is I'm going
to turn off perpendicular again because it gets confused
between tangent and perpendicular.
So I'm going to make it tangent to this circle.
And then I want to make sure it's perpendicular so I have
to change, again, to perpendicular.
That short little line.
So since the shortest line is perpendicular
to the original line and the third line is perpendicular
to the short line, the two long lines are parallel
to each other.
Now I'm going to have to simply extend.
When you extend, it asks you for the boundary first
and then you press enter in between before you click
on the line to extend.
And then, same thing with trim.
OK? I'm going to use the boundaries for circle.
So I click on the circle.
Then that's the trimming edge
and then press enter before clicking on the part
of the line I want to trim.
And I'm going to trim again.
This time, I am going to trim the circle.
So the boundary is those two lines.
Press enter.
And then click on the part of the circle
that I want to trim away.
So I'm going to create a short horizontal line
on the bottom starting from -- I'm going to turn on the snap
so I can rely on my snap.
So from horizontal line, from the middle, from the original
to the tangent of this first line.
Then I'm going to trim that circle.
And then I'm going to mirror all these line segments and arcs.
Press enter.
Then it asks for the line, mirror line,
so I select any vertical line, any vertical line.
Then it asks, "Do you want to erase the source object?"
I don't want to erase, so I'll say n.
Then, finally, I need to trim, again,
with these two lines as the boundary.
Press enter.
And then trim this away.
And then I am done.
