The figure is a square pyramid. It is made with a square on the bottom and 4 triangles meeting at a vertex perpindicular to the square. The square has 1 face, the 4 triangles each have one face making 5 faces. The edges are made where the triangles meet each other and where they each meet the square. There are four vertices at the corners of the square and the one at the top of the pyramid.
An octagonal pyramid has eight triangles on an octagonal base. An octahedron can also be made by putting a square pyramid on another inverted square pyramid. This shape has just eight triangles and no others.
a tetrahedron is made of four triangles and has 4 vertices.
1. a square is made up of two triangles because if you draw a square and draw a diagonal line from right to left or left to right in the middle you will see how two triangles make a square.all sides should be of same length and all bond angles should be 90 in a square.
Make a triangle out of straws or something. See if you can push it sideways like a square. I you try to, you either bend it, break it or push the entire thing sideways... You can't bend it like a square. this is why triangles is the strongest shape. And also tall skyscrapers are made from triangles if looked from a birds eye-view... :D:D:D

If you have 8 small triangles made of 16 lines how can you make four small triangles if it is a parallelogram?
If you draw a single square, and then put one X through it, you have 4 triangles. Put another X through it and you have 8. Now, if you want to make four triangles, simply remove the two diagonal lines in the center, and it will create four triangles. Now, since they're separated by the other triangles, it would mean removing four lines, but that is still your answer.

Still a pyramid!
Rohmbus is a four sided figure (quadrilateral) that is made up of two equilateral triangles
yes

A Rhombus. If it makes two equilateral triangles with a diagonal, the shape must have all four sides of equal length; thus it is a rhombus, possibly a square. As an equilateral triangle is made, the angle between two of the sides is 60o; which is not 90o, so it can't be a square, so it must be a rhombus.
a tetrahedron is made of four triangles and has 4 vertices.
