Which shape is always a rhombus?

am i right
A square because it has 4 sides that are the same length.(my answer)

A rectangle because it has 2 pairs of parallel sides.

An equilateral triangle because it has 3 sides that are the same length.

A quadrilateral because it has 4 sides

Agree

Actually, the correct answer is a rhombus. A rhombus is a quadrilateral with four sides of equal length. While a square also has four sides of equal length, a square is a specific type of rhombus with right angles. Therefore, not all squares are rhombuses, but all rhombuses are squares.
