Create an Octagon From a Square

Draw a square, which is used to draw this octagon.

Step 1: Divide Into Thirds

Divide the lengths into thirds. However, if you want a regular octagon, the lengths must be around the ratio 7:10:7.

Step 2: Split Into 9 Squares

Draw along the markings to create 9 small squares.

Step 3: Make an Octagon in the 9 Squares

Draw lines such that the octagon can be seen in the 9 squares.

Step 4: Erase Forming the Octagon

Erase the unneeded sides such that it forms an octagon.

An octagon has 8 EQUAL sides. This does NOT. The diagonals are longer than the square sides.

wrong method

In this procedure all sides of octagon are not equal

you can see !!!!!!

cool! Just a thought! The diagonals will be sqrt(2) ~1.4 times larger than the the horizontal and vertical sides.
