For this problem, we're asked to construct the perpendicular bisector for all three of these sides.
00:05
I'm first going to start with a, b.
00:08
And you want to go to point a here, move your compass so it's over half the length of a, b, and draw a big arc.
00:17
Then don't move your compass, because you're going to do the same thing on the other side at b.
00:27
And get a straight edge, draw a line that goes through both of those intersection points.
00:40
Okay, so now i'm going to go ahead.
00:41
And change my compass color just to show you.
00:45
And i'm going to do the same thing on bc.
00:47
So this is a little too far here...
