How do you divide a circle with eight equal pieces with three straight lines?


Quick Answer

To divide a circle into eight equal pieces with three straight lines, first draw two diameters that partition the circle into four sections. Next, separate and rearrange the sections, and then use a third line to cut them in half. The line segments inside the circle are chords, and diameters are chords that are in the middle of a circle.

  1. Divide the circle in half

    Draw a light mark at the center of the circle you wish to partition. Use a ruler to draw a horizontal line across this mark. The line is a diameter that divides the circle into two parts.

  2. Divide the circle into quarters

    Place a ruler so that it is perpendicular to the mark. Draw a line from the circle���s top to its bottom so that it splits into four equal parts.

  3. Separate the parts, and rearrange them

    Use a pair of scissors to cut along the diameters in order to separate the pieces. Place these pieces on top of each other so that they form a stack.

  4. Create the eight pieces

    Lightly pencil a line down the middle of the stack���s top piece. Carefully use scissors to cut along this line. The circle should now be split into eight pieces that are the same size.
