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 use 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.
step 1: make a circle with a compass step 2: divide the circle into 4 equal parts step 3: draw curved lines
You draw a circle, and divide it into several equal parts - for example, 4 equal parts. Then you select some of those parts - for example, 3, by drawing them in some special color or shading them. Using a circle is convenient, because then, even if you divide it into pieces, it is visually quite clear that it is part of something greater.
Draw a diameter on the circle from A to B and mark the midpoint, C (center of the circle). Mark the midpoint, D, of one of those radii (halfway between center and edge). Draw a perpendicular line to the diameter from D to the two edges of the circle, E and F. Draw radii from E to C and F to C. Lines AC, EC, and FC mark the three equal parts of a circle.
You can draw 10 equal rectangular parts to draw a square. First, draw a square. Then, split into ten equal portions with the dimension either 2 by 5 or 5 by 2. You cannot draw a square with 10 equal squared parts since 10 is not the perfect square. If we don't have the perfect square number of the equal parts, then we are not able to form a square. Actually, you obtain a rectangle.
If you can draw a line 1 inch long and divide it into 8 equal parts, then each of the segments would be an eighth of an inch long
Draw a + then an X.....then you divided a square into 8 equal parts in one way.
Divide the square into five strips.
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 equal strips.
If you want it divided into five equal parts, draw a dot in the center of the pentagon, and draw a line form each vertex to the dot. You should now have five equal triangles.
Draw a line from midpoint of every other side to the center.
Draw a line from the centre toeach number on a clock face.
draw a + inside it, touching the outside of the circle-cut it into Quaters.
Draw a square and divide it into six equal rectangles, for example: ................................... ... ------------------ ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... | . | . | . | . | . | . | ... ... ------------------ ... ...................................
Draw 2 parallel lines which will result in 3 equal rectangles within the same square.
Select any point inside the hexagon and draw a line segment to any point on the boundary of the hexagon. Draw 7 more such segments. These will divide the hexagon into 8 parts. The parts will not be equal but that was not a requirement of the question.
trisect the bottom side, and draw two lines from the top vertex to the bottom.
draw a circle and cross 12 lines through it like a pizza moron
