Often carpenters and carpenters need geometry in their work.
One of the most striking examples is the construction of a regular circle.
Another problem that can be encountered in this case is the definition of the center of the circle, without resorting to special tools and complex calculations.
You will need
- Ruler and pencil
In order to find the center of the circle, we must first inscribe it into a square. That is, all sides of the quadrilateral must touch the circle. To do this, draw four straight lines using the ruler.
Now connect two opposite corners diagonally. Make sure that the line breaks the corner of the square into two equal parts. Connect all four corners of the square straight.
The intersection point of these lines will be the center of the circle.
Another figure that can helpDetermine the center of the circle, is a rectangular triangle. It also needs to be inscribed in a circle. And then divide the opposite side of the right side in half. The middle of the hypotenuse will be the center of the circle.
