Construction of Perpendicular Lines
Steps to Construct a Perpendicular Bisector
1. 
Draw circle A with a radius greater than
2. 
Copy A with compass tool with to make a new circle with same radius at center B
3.
Label intersections of and as C and D
4. 
Draw line CD
Line CD is the perpendicular bisector of AB
