An isosceles triangle has two equal sides and one different side.
A square
A shape that has 2 pairs of equal sides and no right angles is a kite or a parallelogram. In a parallelogram, each side is equal to the one directly opposite; in a kite, the equal sides are adjacent to one another.
It's either a parallelogram or rhombus
The shape that has not got equal side is a rectangle
It could be a kite or a rhombus. Or, of course, a pentagon with two pairs of equal sides and a different fifth side, or a hexagon, or, ...
A "Math Trapazoid" is a shape that has 4 sides. There is 1 long side on the bottom, 1 medium sized side on the top, and 2 equal slanted sides on the sides of the shape.
Here are three: equilateral triangle, square, and cube
I suggest you go back and check what you want. There is no such thing as an acute side. You cannot have 1 equal obtuse angle (equal to what?).
A trapezoid.
there is no shape with 2 sides. it is an angle.
it has to have equal angles, not side lengths. otherwise it would just be two of the same shape
