Trisecting a line 1. Using a ruler, draw a straight line that starts at one end of the line to be trisected (the "original" line) and forms an angle with it that is som…e number of degrees less than 90. 2. Using a compass (the drawing kind, not the navigating kind), set some distance on it, say, 2 inches. 3. Putting the point at the intersection of the original line and the one you just drew, make a mark with the pencil end that intersects the line you just drew. Place the point on that intersection point and repeat. Now move the compass and repeat again. 4. From the point at which your third mark intersects the line you drew in step 1, draw a straight line to the end of the original line. 5. Using a protractor, measure the angle formed by the line you drew at step 1 and the step 4 line. 6. With the protractor draw a line from the second mark to the original line that has the same angle as the line in step 5. 7. With the protractor draw a line from the first mark to the original line that has the same angle as the line in step 5. 8. Take a break!

Divide 3 inches in 5 equal parts
90 degree bisector
Select any one side and divide its length into 5 equal parts. Draw lines that are parallel to the adjacent side to the opposite side. This will divide the rectangle into 5 equ…al strips.
The point that divides a line segment into two equal parts is called the midpoint. |________________|________________| Let the first vertical line, | , represent point A. Le…t the second vertical line represent point C. Let the third vertical line represent point B. Before we divided this line, it was segment AB. The MIDPOINT, C, divided it into two equal parts.
The number of degrees in one complete revolution of a radius is 360°. Therefore the number of degrees covered in 1/5 of a revolution is 72° . To divide a circle into 5 equal… parts create 5 sectors each measuring 72° at the centre of the circle.
Measure it and then divide the number by 4 so you will know how far you nedd to cut it
5*20 cm=1 meter
Select any one side. Divide its length into 5 equal parts. Do the same to the opposite side. Join the corresponding divisions. You will then have 5 equal rectangular divisions… of the square.
Use a ruler to measure the line (horizontal?) and mark the middle of the line, then use a right-angle triangle to draw a vertical line 90 degrees from the mark. Or you can u…se a compass fitted with a pencil to draw arcs that will give the middle mark and a mark to line a ruler against to draw the perpendicular line required. Search Google for using a compass.
The Equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Lines of latitude are parallel to the Equator both to the north and to the south.
