a square, altough to get it to look like a "diamond" you would have to look at it diagonally.
Not sure what a dimond shapiro is, but I guess the answer is a rhombus.
it is called a isosceles shape if iT only has 2 sides that have the same exact length
The sides of a rhombus must all be the same length, but the angles do not need to be the same. The result is a diamond shape where the diagonals can be two different lengths.
A kite or arrowhead.
A four-sided shape with only 2 sides the same length is called a rhombus.
It's a shape with many sides where all the sides are the same length.
