3 triangles make up a hexagon.
Hexagonal prisms cannot be regular. If you tried to make one it would end up being a hexagon since six equilateral triangles make a hexagon. Therefore, there is no surface area.
There are an infinite number of options. Even sticking with polygons with sides of the same measure, a hexagon can be made from 6 equilateral triangles, or 4 eq triangles and a 60 degree rhombus, or 2 eq triangles and 2 60-deg rhombi, or 3 60-deg rhombi. Each of the equilateral triangle could be made from smaller shapes. Eg four equilateral mini-triangles to make 1 triangle. Or 2 mini-triangles and 1 mini-rhombus or 2 60-deg mini-rhombi. And then each of those mini triangles could be made up of smaller micro-shapes. And so on ...

Four equilateral triangles make up another equilateral triangle.
It's easy all you have to do is make a heart shape
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.
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.
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.
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.
