There is no specific name for any shape that has only two equal sides. How many other sides does it have? Are these other sides straight of curved? You have chosen not to provide any of this information and so I regret that it is impossible to give a more useful answer.
Another Answer:-
It could be an isosceles triangle that you have in mind.
A rhombus is the only shape besides a square that can have equal sides.
When all sides are equal it has a to be SQUARE. Which is the only shape that is a regular quadrilateral.
No. An isosceles triangle has two equal sides but only one line of symmetry.
It is an isosceles triangle
A nine sided nonagon is only a regular shape if it has 9 equal sides

That shape would be a trapezoid.

An isosceles triangle.
Any shape with more than 3 sides can have two pairs of equal sides and no right angles. If it only has 4 sides in total and isn't a parallelogram, then it's a trapezoid.
A 6 sided hexagon is only a regular shape if it has 6 equal sides otherwise it is an irregular shape.
A shape that has two pairs of opposite sides that are equal is a parallelogram. This includes specific types of parallelograms such as rectangles and rhombuses, where the opposite sides are not only equal in length but also have specific angles or properties. In general, all parallelograms have this characteristic property of equal opposite sides.
