CONSTRUCTION OF A TANGENT
Given: Circle O
Construct: a tangent to circle O from P
Construct: a tangent to circle O from P
STEPS:
1. Connect O to P.
2. Construct bisector of 
.
3. Place compass point at midpoint of and stretch span to O or P.
4. Draw circle.
5. Connect P to where the two circles intersect to create tangents.
