Draw a rectangle in the ratio of 1:2 eg sides of 5cm & 10cm. Bisect both the longer sides and join their mid points with a straight line. Draw a diagonal. This gives you 2 squares, 2 big triangles and 2 small triangle (1 in each square)
You Can Get 6 triangles
6 triangles is 18 and 3 squares is 12 18 +12 ------- 30
pentagon i think?
Yes. The triangles have the same angle measures but different, similar side lengths. Think of two different sized equilateral triangles. One can have side lengths of 6 inches while the other has side lengths of 20 inches, but they still have congruent angles of 60 degrees. Each ratio of side lengths is equal [6/20=6/20=6/20].
6 straight lines drawn inside of an octagon will divide the octagon into 8 triangles
draw two triangles with overlapping lines
6 straight lines drawn inside of an irregular octagon will produce the desired result

No it is not. A polygon is a plane space enclosed by straight lines. A pentgram is not one enclosed space but 6 spaces - a pentagon and 5 triangles.
There are 16 possible triangles.
Draw a line from the midpoint of each side of the triangle to opposite corner. All three lines should intersect at the center of the original triangle and six smaller triangles will be formed. There are likely other solutions, but this is the easiest one.
never tried it without my Gay lines so I wouldn't know for sure, but try 3 and see what you get
By showing him how to do it.
It is: 8-2 = 6 triangles
