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.
Know MoreDraw 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.
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.
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.
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.
According to Programmer Interview, the circle must be cut into quarters using the first two cuts, and then the quarters must be stacked into one pile before making the last cut. This is done by stacking the pieces of the circle.
Full Answer >To find the area of a sector, divide the angle of the sector by 360 degrees, then multiply the answer by pi and the square of the radius. You need to know the angle and radius of the circle. A ruler, a calculator and a protractor are helpful in this task.
Full Answer >To make Dookie braids, also called box braids, divide the hair into four sections, clip three of them, and fill the fourth section with tiny braids from the roots to the tips. Secure the braids with rubber bands, and repeat with the remaining sections. This two-hour procedure requires rubber bands, a styling comb and hair clips.
Full Answer >Tessellations occur when a shape is repeated in an interlocking pattern that fully covers a flat surface, or plane, like the pieces of a puzzle. Some shapes cannot tessellate because they are not regular polygons or do not contain vertices (corner points). They therefore cannot be arranged on a plane without overlapping or leaving some space uncovered. Due to its rounded edges and lack of vertices, the circle is normally not tessellated.
