It is called the Point of Origin.
The fixed point that is located in the center of a circle and is used as the guiding point to draw it is called the "point of origin".
To find the center of a circle for drilling, you can use a compass to draw two intersecting lines across the circle. The point where the lines meet is the center of the circle. You can then mark this point for drilling.
To draw a great circle on a sphere, start by defining the diameter as the largest circle that can be drawn on the sphere's surface. For small circles, choose a point on the sphere and draw a circle with that point as the center and the radius less than the sphere's radius. Remember that the center of a small circle lies outside the circle on a sphere's surface.
If you know the radius place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle. If you know the diameter divide by two to get the radius and place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle.
To mark the center of a circle accurately, use a compass to draw two intersecting lines across the circle. The point where the lines meet is the center of the circle.
Circle
Yes, you can draw a circle with a dot in the middle by first using a compass to create a perfect circle. Place the compass point at the center of where you want the circle, adjust the other arm to your desired radius, and rotate it 360 degrees. After completing the circle, simply place a dot in the center where the compass point was located. Alternatively, you can draw the circle freehand and then use a pen or pencil to add a dot in the middle.

An easy way to draw a pie is by first drawing a circle. Next, use lines to divide the circle into slices.
A compass
To prove that segments ( ab ) and ( ac ) are congruent in the construction of an equilateral triangle, you can use the property of circles. When you draw a circle with center ( a ) and radius ( ab ), point ( b ) lies on this circle. Similarly, if you draw a circle with center ( a ) and radius ( ac ), point ( c ) lies on this circle as well. Since both circles are constructed with the same radius from point ( a ), it follows that ( ab = ac ), proving that segments ( ab ) and ( ac ) are congruent.
