Draw a line sideways for the top side then draw a diagonal going out on either end of the other line then draw a line downwards from that line then draw another diagonal line going inwards from the line before then draw a straight line across on that one then a diagonal line outwards on that line then do a line going up on the before then do a diagonal line inwards joining the before and the starting line
A quicker way
draw two equal sized squares. place one over the other (properly centered) and turn the top one 45 degrees (clockwise or counter-clockwise, your choice) draw along the edge of the top square where it crosses the exposed parts of the lower square. Remove the top square, erase the "points of the lower square and what remains is a perfect octagon.

Simply draw eight straight lines that meet pairwise to form eight vertices. The answer from V A Nicholsson is an excellent answer for drawing a regular octagon, but the question is about an octagon which is not necessarily regular.
draw an octagon then erase one corner and connect it
Oh honey, an octagon has eight sides, so you can't exactly divide it into thirds. But if you want to divide it into equal parts, you can draw lines from opposite corners to create six triangles, which are the closest thing you'll get to thirds in an octagon. Math can be a real party pooper sometimes, huh?
actually its really hard and scientist know how but they still dont know the answer but i can still tell you how to do it first you need to draw a perfect octagon after that you draw tiny little bity squares inside it all being the same size not a tad off then find how many square milimeters one of them has and times that by how many squares you drew you then you draw that ammount of those size of squares of the answer then you draw a circle around that and you find the circumpherence of that circle and time that circumpherence by 3.14 i know what you are think why would we do that when we did it for the circle all ready but you have to do it again for the octagon

In an octagon, there are 20 equilateral triangles. Each side of the octagon can form two equilateral triangles with the adjacent sides, resulting in 8 equilateral triangles. Additionally, the diagonals of the octagon can form 12 more equilateral triangles. Therefore, the total number of equilateral triangles in an octagon is 8 + 12 = 20.
