Nine, as a n-gon can be cut in n-2 triangles.
Yes, you can but it take 3 triangles.
It needs only 2 triangles to construct a parallelogram
2 triangles make up a rhombus which has 4 interior angles adding to 360 degrees and a triangles has 3 interior angles add up to 180 degrees. Therefore: 360/180 = 2 triangles
10 sides and angles * * * * * A decagon need not have any equal sides. If it does have equal sides, their number can take any [integer] value in the range [2, 10].

4 triangles make 1 hexagon. (easy way to find out how many triangles there are in a polygon- take number of sides of the polygon, subtract 2 from it, that's your answer!)

4, one for each side face
It needs only 2 triangles to construct a parallelogram
A minimum of 2 triangles are needed, but you can also make a rectangle with 3 or more triangles.

Yes.
to make a model of a food pyramid take a cardboard and cut it in 3 triangles and then make a triangle shape with those triangles,then go to the web and search pic of foodpyramid
take three match for each triangle
