Six. This is true even if the triangle is thin, flat, or scalene, unless it's an unusual tesselation.
The tessellating shape can have 3, 4 or 6 sides.

There are infinitely many even on the plane and infintely more in space.For Example:Take a square, draw the diagonals.The meeting point of the dialgonals is the vertex where three polygons (in this case triangles) meet.
an infinite number
Infinitely many. There are infinitely many points in the plane and although any pair of points define a line, no matter how many lines you are given, it is always possible to find a point that is not on any of them - that is, a point that is not collinear.
The tessellating shape can have 3, 4 or 6 sides.
all of the quadrilaterals, triangles, and many more. In fact, all the polygons.are plane figuresl
Four of them

2 shapes; 1 square base and 4 triangles.
The least number of obtuse triangles, if all possible triangles are drawn for n points in a plane, is zero. If all the n points lie in a straight line, no triangles are possible and so no obtuse triangles are able to be drawn; thus for any number n, there is a possibility that no obtuse triangles can be drawn, so the least possible number of obtuse triangles drawn is zero.

There are 48 triangles that can be formed because 6 triangles can be formed usin each point multiplied by 8.
There are infinitely many even on the plane and infintely more in space.For Example:Take a square, draw the diagonals.The meeting point of the dialgonals is the vertex where three polygons (in this case triangles) meet.
A trapezoid contains three triangles, or more depending on how you divide it. Where its longer parallel side is at the bottom, two triangles point up and one points down.
Infinitely many. Given any triangle, a line from a vertex to any point on the opposite side will give two triangles. That process can continue indefinitely.
