Every square is a rhombus, but every rhombus is not a square.
A square must have all right angles and a rhombus does not.
A rhombus is a quadrilateral which has all sides congruent. It can have oblique angles or right angles. A rhombus with right angles is a square. Other rhombi are not squares.
By these definitions, all squares are rhombi, but not all rhombi are squares

yes.
Quadrilateral: a 4 sided figure
Parallelogram: a quadrilateral with all sides parallel
Rectangle: a parallelogram with 4 right angles
Rhombus: a parallelogram with all sides equal
Square: a rectangle and rhombus
yes all squares are rhombuses but not all rhombuses are squares
All squares are rhombuses. A square is a special case of a rhombus with adjacent sides at right-angles. yes, squares are rhombuses.
Are all rectangles parallelograms
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
The main thing squares and rhombuses have in common is that they have congruent sides all they way around. The only difference, however, is that squares have 90-degree angles, whereas rhombuses have 2 sets of congruent angles not equal to 90-degrees. They are also both polygons and all their internal angles adds up to 360.
