h a diameter connecting points A and C .
What is Omar's next step in the construction?
A
Starting at point A , use the compass with a setting of the length of the radius to mark off the radius four times around the circle.
B
Use OA¯¯¯¯¯ to construct a line tangent to the circle at point A .
C
Construct a perpendicular bisector of AC¯¯¯¯¯ , making it long enough to touch the circle above and below the diameter.
D
Construct a perpendicular bisector of OC¯¯¯¯¯ , making it long enough to touch the circle above and below the diameter.
