 In this video we're going to look at how to bisect an angle. You just need a compass, pencil and a ruler. We're at the space station on Mars. We want to build a path that is equal distance from the edges of our boundary. We need to bisect the angle to make sure that we are exactly in the middle. Bisect just means cut in half. Put your compass on the point and draw an arc to cross both boundaries. Then put your compass at the first place where the arc crosses the line and draw another arc. Repeat this for the second point making sure you do not change the width of your compass. You end up with two new arcs that cross each other. Where these arcs cross is the angle bisector. With your ruler, draw on the line. So we now know exactly where our path has to go. It's quite easy really. You just need to remember to draw two sets of arcs and then you have bisected the angle.
