Any three angles that sum to 180 can form a triangle.
As many as you like. Wherever you have one triangle, you can draw a line from any vertex to the opposite side and so end up with one more triangle.
Yes, they can. A simple test would be that any two sides added together should be more than the third side. If not, then it cannot form a triangle.
They are the points where pairs of sides come together, just as they are in any triangle.
any three that connect
yes
no two triangles can make a square
Yes,put a triangle on a flat surfaceput another triangle underneath the other triangle and look at itit makes a rhombus but you have to turn it side waysRHOMBUS
I am a rhombus or an equillateral triangle, pentagon, hexagon, octagon etc.

no a equilateral triangle does not have any perpendicular sides because the lines are joined together.
They are the points where pairs of sides come together, just as they are in any triangle.
