There are infinitely many such shapes.
Faces are sides of 3-dimensional objects. If these faces are four bounded by four straight lines then they are quadrilateral faces.
Some types of quadrilaterals don't have parallel sides. Such as a diamond or a kite.
Simpy, some do and some don't. Quadrilaterals are any four sided figure. A square has all four sides equal, while a rectangle and a trapazoid have 2 sets of equal sides.
Some shapes having four equal sides include rhombus, square, diamond, parallelogram with four equal sides, and oblique-angled equilateral parallelogram.
There are infinitely many such shapes.
the base consists of four sides and they are both 3 dimensional objects.
Faces are sides of 3-dimensional objects. If these faces are four bounded by four straight lines then they are quadrilateral faces.
All polygons
The pyramids have triangular sides but four sides.
A quadrilateral has four sides, and so four quadrilaterals will have a total of 16 sides counted separately.
Some types of quadrilaterals don't have parallel sides. Such as a diamond or a kite.
Simpy, some do and some don't. Quadrilaterals are any four sided figure. A square has all four sides equal, while a rectangle and a trapazoid have 2 sets of equal sides.
it is a square, rectangle & some of the parallelogram.
A parallelogram with four congruent sides would be a square, some rhombi, and some rhomboids.
Some shapes having four equal sides include rhombus, square, diamond, parallelogram with four equal sides, and oblique-angled equilateral parallelogram.
No but a trapezoid does belongs to the class of 4 sided quadrilaterals.
