making an octagon using diamond shapes
They're both shapes... ;) Also: the sum of the angles that make them up fit the equation 180(x-2) where x is the number of sides. E.g. a triangle has 3 sides so the total angle sum is 180. An octagon has 5 sides so the total angle quantity is 900.
Five shapes that can be constructed are octagon, hexagon, square, triangle, and rectangle.
Eight triangles of equal size form a regular octagon.
There are hundreds of shapes; some shapes are square, triangle, circle, rectangle, oval, octagon, hexagon, pentagon, cube, cylinder, and lots of combinations of shapes that form new shapes.

An octagon
an polygon
They are both shapes and an octagon can be made up of six or more triangles. Other than that they are not similar. A triangle must have three sides. An octagon must have eight sides.
