There would be arrows connecting the Rectangle to the Square and the Rhombus to the square, again indicating that sometimes a rectangle is square and sometimes a rhombus is a square. If the shape is below another, then it is always the shape above it as well. So a rhombus is always a parallelogram, a square is always a rectangle, and always a parallelogram, and always a quadrilateral, etc. If I could draw the arrows in this reply it would look better. Also, we have gone through the definitions of each special quadrilateral before we look at the hierarchy
a rhombus has two lines of symmetry because two lines pass through the corners of a rhombus there are some properties of rhombus which are as follows base in a rhombus we can assume as a base of rhombus if we want to find the area of a rhombus then we have to use the altitude of a rhombus
