CD is the perpendicular bisector of another line AB which can be proven below.
What is perpendicular bisector?
Perpendicular bisector is a line that divides another line into two equal halves in such a way that it creates an angel of 90°.
To proof that CD is the perpendicular bisector of another line AB the following is carried out;
- Draw a line segment AB with length of about 5 cm.
- With any radius greater than 2.5 cm, and compass fixed at A, draw 2 arcs, one above and one below AB.
- With the same radius, compass at B, cut the 2 arcs drawn in step 2.
- The line joining these two arcs is the perpendicular bisector of AB.
