The first thing you need to do is to grab a pencil and a blank paper or chart. Draw a regular hexagon. Try to draw it as cleanly as possible. Use a ruler to make sure that the lines are as straight as possible.
After you have drawn the hexagon, use the ruler to divide the hexagon into six triangles. Dividing the hexagon into triangles can prove to be a bit tricky. Connect diagonal corners of the hexagon with each other through a straight line. If you are still confused about how the hexagon should be divided into triangles, bring an image of a pizza and its division into slices into your mind. Now imagine that the hexagon is a pizza that you have to divide into six equal slices. Hopefully you will have no problem dividing it into triangles now.
After you have successfully divided the hexagon into six triangles, colour two triangles right next to each other, say green. Now use a different colour to colour two more triangles, also right next to each other. Use a third different colour to colour the remaining two triangles, which will obviously be right next to each other as well.
Now use a relatively thicker pencil to make the hexagon as well as the lines separating the different colours prominent. Remember, you have to outline the lines between the colours and not the segments with the thick pencil.
After you have darkened the lines of the hexagon and the lines between different colours, use a normal pencil eraser to erase the lines between each colour’s segments. Again, do not confuse the lines in the segment from the lines separating the different colours. Make sure you use a normal pencil eraser and not the colour eraser to erase the lines.
