The answer could depend on the way in which the shapes are connected but I doubt that it has any specific name.
Some of them are: triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, decagon ..... etc
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.
No. All 2-dimensional shpaes with 8 sides are octagons; all 3-dimensional shapes with 8 sides are called octahedrons.
Three is to triangle as eight is to octagon.
An octagon has eight sides.
Assuming they don't overlap, and depending on their exact dimensions, these are some of the possible shapes: A triangle (big) A square A rectangle A parallelogram A rhombus A trapezium A pentagon A hexagon A heptagon and if a vertex of the triangle rests on the side of the trapezium, an octagon. a concave pentagon, a trapezium, a concave seven or eight sided figure (neither of the last two is a polygon but two polygons touching one another)
An octagon
Eight, possibly.
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.
It is a right angle triangle.

A shape with eight sides is called an octagon.
