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
take three match for each triangle

To form a hexagon, you would need a total of 6 triangles. Each side of the hexagon would be made up of one triangle, so when you combine all six sides, it creates a hexagon. This is because a hexagon is a polygon with six sides and six angles, and each side is made up of a single triangle.

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

A minimum of 2 triangles are needed, but you can also make a rectangle with 3 or more triangles.

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
it would have 18 triangles because u take 2 away each time.
