Basic geometric tasks can be performed if you find the center of a circle.There are many ways to find the center point.You can use a ruler, draw crossed lines, or draw circles.
Step 1: A circle is drawn.
You can use a compass or trace an object.The size of the circle doesn't matter.You don't need to draw a new circle if you find the center of an existing circle.A geometry compass is used to draw and measure circles.You can buy one at a school or office supply store.
Step 2: Take a picture between two points.
There are two points along the edge of a curve.The name is AB.If you want to sketch your lines, use a pencil.Once you've found the center, you can erase the marks.It will be easier to erase if you draw with a light touch.
Step 3: A second chord can be drawn.
The line should be the same length as the first one.This is a new CD.
Step 4: There is another line between A and C.
The AC should stretch through the center of the circle, but you will need to draw one more line to find it.
Step 5: Join B and D.
You should draw a new line across the circle between Point B and Point D.
Step 6: Find the center.
If you have drawn straight lines, the center of the circle is at the intersection of AC and BD.Use a pen or pencil to mark the center point.If you only want the center point marked, then you should remove the four chords that you drew.
Step 7: The two points should be drawn between them.
A straight line can be drawn from one edge to another using a ruler or straightedge.The points you use don't matter.There are two points A and B.
Step 8: A compass can be used to draw two circles.
The circles should be the same size.Make A and B the center of the circle.The two circles should overlap like a diagram.The circles are drawn in pencil.If you can erase these circles later on, the process will be simpler.
Step 9: The circles intersect at two points where you can draw a vertical line.
There are two points at the top and bottom of the "Venn diagram" space.To make sure the line protrudes straight through the points, use a ruler.Finally, label the two points at which this new line crosses the rim of the original circle.The diameter of the original circle is marked by this line.
Step 10: The two circles should be erased.
For the next step of the process, this should clear up your work space.You should have a circle with two lines running through it.The center points of these circles should not be erased.Two new circles will be drawn by you.
Step 11: There are two new circles.
If you use your compass, you can draw two equal circles with the same point.The points at which the vertical line intersects the main circle are called C and D.
Step 12: There are points at which the new circles intersect.
The overlap space of the two new circles should be cut through by this straight, horizontal line.The second diameter line should be the same diameter as the first one.
Step 13: The center is to be found.
The intersection point is the center of the circle.This is the center point for reference.If you want to clean up the page, you can remove the diameter lines and non-original circles.
Step 14: There are two intersecting lines on the circle.
The lines can be random.The process will be easier if you make them square or rectangular.
Step 15: To the other side of the circle, translate the lines.
Four lines will form a parallelogram or a rough rectangle.
Step 16: The diagonals of the parallelogram can be drawn.
The circle's center is where the diagonal lines intersect.
Step 17: The accuracy of the center can be checked with a compass.
If you don't slip while drawing the diagonals or translate the lines, the center should be on target.The parallelogram and diagonal lines can be erased.
