Two triangles can but its an irregular shape
Put four equilateral triangles so that each one of them has a vertex at a single point and the triangles abut one another. The shape will be 4/6 (= 2/3) of a regular hexagon.
Well, isn't that just a happy little challenge! To make a heptagon out of six equilateral triangles, you can start by arranging the triangles in a circular pattern with their edges touching. Then, you can add a seventh equilateral triangle on top to complete the shape. Remember, there are no mistakes, just happy accidents in art!
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!)

You Cant. Because A Hexagon Is A Six Sided Shape. And An Equilateral Triangle Is Equal. So You Can Because Everything (As In Sides And Angles Will Be Congruent)
No but they will make a hexagon
First make a regular hexagon. Then take any one triangle and slide it through two heights so that it's base is on what was the opposite side. You will have an irregular, concave hexagon, shaped somewhat like an arrowhead.
Join them together
you can't
Two triangles can but its an irregular shape
Put one angle of each triangle at the center of the hexagon.
You take four regular triangles and make the all on the same center point and make them share one or two of there side with the triangle next to it until you get something that looks like a pac-man with a big mouth.
Infinitely many. When you have one equilateral triangle, you can join up the midpoints of its sides to make into 4 more equilateral triangles. And then each one of those can be split up and so on.

A regular hexagon can be considered as being built up of six equilateral triangles. Each equilateral triangle has an area of (b/2) * sqrt (3b/2) where b is the side of the equilateral triangles that make up the hexagon and also the radius of the hexagon's circumscribed circle, and sqrt means the square root ofSo the area of the regular hexagon with side length b is 3 * b * sqrt (3b/2)
No two equilateral triangles do not make a square but two right triangles do.
