A square and a rectangle have diagonals of equal lengths
rhombus
You are a square
A shape with four sides and perpendicular diagonals is called a rhombus. In a rhombus, all sides are of equal length, and the diagonals bisect each other at right angles. Additionally, the diagonals are not necessarily of equal length, which distinguishes a rhombus from a square.

Check to see that -- it has four sides -- its two diagonals are equal.
A parallelogram perhaps?
It is a rhombus
Yes, the diagonals of an isosceles trapezoid are equal in length. An isosceles trapezoid has one pair of parallel sides and the non-parallel sides (the legs) are of equal length, which leads to the diagonals being congruent. This property arises from the symmetry of the shape.
