How can a figure be a rectangle, a rhombus, and a square?

Question

Explain how a figure can be a rectangle, a rhombus, and a square.

Answer 1

A rhombus has four sides all the same length.

  -  Does a square have four sides of equal length?

A rectangle has four right angles.

  - Does a square have four right angles?

A square has four equal sides and four right angles.

  - Does a square fit the definition of a rhombus and a rectangle?

 

Not all rhombuses are squares because they do not all have four right angles.

Not all rectangles are squares because they do not all have four equal sides.

Not all rectangles are rhombuses because they do not all have four equal sides.

 

But all squares are rhombuses and all squares are rectangles.
