I’ve heard people say ‘What great are discovering things in college if you don’t use them?’. After ~ my life time of careers, ns realize you never understand what may be beneficial to you later. Among my most valuable high school classes because that example, to be a one-semester course in inputting – a ‘fill-in’ food – means back when they taught ‘Typing’. Ns guess that is dubbed ‘keyboarding’ if anything similar is even taught today.

You are watching: How to divide anything into equal parts

Geometry was another, which at the time I learned it I might see no useful use for. But, together it transforms out I provided geometry in exercise a great deal in mine boatbuilding career, an especially in layout work. Give thanks to goodness, sufficient of it stuck over the years to be very useful.

Case in point: splitting a line (or space) right into equal parts;

Sometimes you should divide a line, an are or length right into a number of smaller parts, all same to every other. Because that example, suppose you have a an are or piece of material 27-7/8” lengthy which you should divide into 5 equal parts. You have the right to do this mathematically and end up v each part needing to be precisely 5.575” long. But, currently you must convert this into English measurement equivalents (inches and also fractions) and then shot to measure these divisions with your ruler or scale. This is really hard to do accurately. Oddly, many usual dimensions are hard to divide using English procedures – for instance 24” by 5 or 7 (4.8” & approx. 3.43”).

(And, let me speak right here as one aside, that also though I have lived with English measurements all my life, things space much much easier using metrics! among all nations, just Burma, Sierra Leone and the US have actually never officially embraced the global metric device . . . ! the being said, you can buy ‘engineers’ scales which divide English measurements into tenths, but few besides engineers and machinists use those.)

But, ago to my example; in three steps, you can quickly and also easily divide any length through any number of divisions graphically using straightforward geometry. Because that those who are not familiar with this, I current it come you here:

1. Create (draw) lines in ~ either finish of your size or an are to be divided, and also at best angles (perpendicular) to it. See image #1.


(Image 1 – an are to be divided)

2. Ar your ruler or scale between the two perpendiculars and angle it until you have actually a measurement you can conveniently divide by the number of equal spaces needed. For Instance, in the example above, you can conveniently use 30” and divide the by 5” increments to acquire 6 same divisions. (Or, by 7-1/2” increments for four divisions, by 5” for six divisions, by 1” for thirty divisions and so on.) See photo #2 & #3.

3. Mark these clues (I constantly use a quick line against the scale with a tic mark at the point for accuracy), and also lines attracted at appropriate angles native the original line (or space), with your points gives the same divisions. Experienced cuts centered on these lines will make exactly equal components if you are sufficiently careful. See image #4:

If you need to divide a plank right into a number of equal widths, you might use one of two people edge of the plank together your ‘perpendiculars’. Slant your scale and also divide across from edge to edge in ~ each end of her plank, and lines attracted with a right edge through equivalent points will certainly divide the plank right into equal widths. A little thought shows you can also lay out a number of exactly same tapers through adjusting the length of one finish point! See photo #5.
