squares and rectangles.
Only if 2 sides are parallel with each other, and the other two sides are also parallel with each other. All squares are rectangles. All rectangles are parallelograms. All parallelograms are 4 sided. But not all 4-sided are parallelograms, not all parallelograms are rectangles, and not all rectangles are squares.
No, not all quadrilaterals are rectangles. Quadrilaterals are any shapes that have four angles and sides. While not all quadrilaterals are rectangles, all rectangles have to be quadrilaterals.No, but a rectangle is in the family of 4 sided quadrilateralsNo. A quadrilateral is a rectangle only if its angles are all equal.no
A diamond (not dimond) has 1 face, 4 sides and 4 vertices.
A rectangle is a quadrilateral that has four sides.
Rectangles must always have 4 sides. As there are two rectangles, there must be 8 sides. However, if these two rectangles have identical sized sides and they are placed against each other so that they look like one rectangle, there will only be 4 sides.
Providing they are not contiguous there are 16
4 sides
All rectangles are quadrilaterals. A quadrilateral has 4 sides; all rectangles have 4 sides; thus all rectangles are quadrilaterals.
A parallelogram has 4 sides
a quadralateral has 4 sides
All rectangles have 4 sides. All parallelograms have 4 sides. A rectangle is a parallelogram with all 4 angles of 90°

4 sides and 4 interior angles
Well, squares do have equal sides but rectangles have two pairs of equal sides
