A rectangle has right angles, a rhombus may not. A rhombus has 4 equal sides, a rectangle might not, if it does it is a square,
Most rectangles are not rhombuses, but there is a shape that has all the properties of a rectangle and all the properties of a rhombus at the same time. It is called a square. A square is a special rectangle and a special rhombus.
It is a square, a rectangle, or a rhombus. Also known as parallelograms.Parallelogram--includes rectangles, rhombuses, squares, etc.
No. A rectangle has all angles equal to 90o; a rhombus has opposite angles equal but they do not need to be 90o; thus all rhombuses are not rectangles. All rectangles have four equal angles and opposite sides of equal length, all four sides need not be the same length; a rhombus has all 4 sides of equal length; thus all rectangles are not rhombuses either.
This is false. Every rectangle is a parallelogram, but the converse (your statement) is not true. Imagine the set of all quadrilaterals (4 sided polygons). Within that set would be sets of kites, parallelograms, and other quadrilaterals. Within the parallelogram set, would be rectangles, rhombuses and other parallelograms. Then if a rhombus is also a rectangle, it would be a square, that would be the intersection of the set of rectangles and set of rhombuses. Hope this helps.
