# How do you find the center point of a circle?

Draw a cord through the circle (a line through the circle, but not too close to where you imagine the center to be). With construction techniques, find the perpendicular at the center point of the cord, and draw the perpendicular. Do the same thing again starting with a different cord, and the two perpendiculars will intersect at the center of the circle.

The circumference of a circle is found by the use of a
protractor. Placing the
point of the protractor at what will be the center of the
circle, the point is held
steady while the two arms of the protractor are turned around,
marking the
circle as the protractor turns.
When this exercise is finished, the point is in the middle of
the circumference, and the circumference figure is measured at any
point on the outside circle of the
circle, to the point in the center of the circle. This is the
measuring of the
circumference, from the center point to any other point on the
circle.
This is done by the study of plane geometry.
