On a plane surface you cannot. Assuming you mean a right angle when you say a square corner, it is not possible.
No. It is not possible to make a equilateral triangle that is obtuse.
An equilateral triangle has all equal sides. "Equal"ateral
draw a square with an equilateral triangle (the side must be as big as the side of the cube) joined by its side on all sides.
a larger equilateral triangle
It seems that if you can make 1, then you can make 3 .
make six equilateral triangles depending on the size edit: If it is an equilateral triangle, draw a line from each corner to the centre of the opposite side.

Four equilateral triangles make up another equilateral triangle.
Two. One big square and a smaller one inside to make a corner into a triangle.
an isosceles triangle has 2 equal sides while the equilateral triangle has 3 equal sides
Yes, they can. To demonstrate this draw a square on a sheet of paper. Draw a line diagonally from one corner to the one opposite. Cut along this line and you will have two triangles. Take them apart; if you put them together again in the right way you will have a square. Put together in different ways you can make an isosceles triangle or an equilateral parallelogram. If you do the same thing beginning with a rectangle, you will be able to reassemble the triangles to form a rectangle, isosceles triangle or a (non-equilateral) parallelogram.

a larger equilateral triangle
Yes. Acute angle is less than 90°. 60° which is less than 90°, can make an equilateral triangle .
because it has angles so you can't make a triangle
No two equilateral triangles do not make a square but two right triangles do.
