Perpendicular bisector of a line segment:
The locus of a point which moves so that it is an equal distance from two points, A and B, is the perpendicular bisector of the line joining A and B
Perpendicular mean at right angles to
Bisector means cuts in half
To construct this locus, you do the following:
Put your compass on X and set it to be over half way along the line. Draw an arc
Label these points A and B
The point M where the lines cross is the midpoint of XY. And AB is perpendicular to XY
V is the vertex of the angle we want to bisect
Label the crossing points A and B
Without adjusting your compass place it n B and draw another arc that cuts off the one you just drew. Label the point where they cross C
The line VC bisects the angle. Angles AVC and BVC are equal
