The shape you're describing is an isosceles triangle. It has three sides, with two sides being equal in length, and the third side being different. An isosceles triangle typically does not have rational symmetry, as its symmetry is limited to a single axis of reflection through the vertex opposite the base.
The shape has to be a parallelogram since it has no lines of symmetry and all sides are equal and parallel
No. An isosceles triangle has two equal sides but only one line of symmetry.
