It depends on the dimensions of the 7 shapes.
A diamond is not a rigid shape unless it has a brace. A brace is a diagonal line you put inside shapes to make them rigid. Triangles are rigid so if you put a brace in a square to make two triangles the square is now rigid.
No two equilateral triangles do not make a square but two right triangles do.
You can make a square, a rhombus, a parrallelogram, a kite, a rectangle, and a trapezoid. If you were to make all these shapes out of two triangles, you would have to have different sized triangles for most of them. If you put the bottoms of both of them together, it will make a diamond shape. But they would have to be the same size.
does 4 go into a diamond
can two triangles put together make a square
put the triangles upside own under neathe the square the make the trapezoid the head the last triangles the ears
A square already has 2 right angle triangles within it
you can make a square based pyramid using 4 triangles and a 1 square
They are 4 triangles and one square. What they might make when assembled together depends on their sizes and on the shapes of the triangles.
How many triangies make a diamond?
two
a square
