no they are all 5 sided!

Pyramids may appear four sided but they actually not. The reason they appear four sided in pictures and videos is because of the distance the shots were taken. On closer look, they have about eight sides. Some people believe this multiple sides actually keep the pyramids for this long and also protects them from being affected by tectonic movements
Las pirámides no son iguales. Hay que tener en cuenta que antiguamente una de las mayores incógnitas era el cielo. Muchas civilizaciones se preguntaban qué sería, qué habría etc. y la cuestión es que no todos construían las pirámides de la misma manera.
they are: ---sided pyramids and triangular prisms and 20 sided 3d shapes
There are many four sided figures that are named some are:squarerectangletrapezoidparallelogramrhombkiteAll of these are called quadrilaterals
Generally a four sided object is called quadrilateral. Some examples of four sided objects are square, rectangle, parallelogram, rhombus, trapezium, etc.
Fact there IS such thing as four sided triangles, no they aren't polygon's yes they are triangles, do some research on it?
rectangle
Some missions were built as four sided enclosures. The inside would then be a four-sided open space which is called a quadrangle.
The pyramids have triangular sides but four sides.
Any four-sided shape is a Quadrilateral. Some other examples are: square rhombus parallelogram quadrangle rhomboid rectangle oblong kite trapezium trapezoid
a polygon is ANY note the any four sided figure.
All squares and rectangles are quadrilaterals. The of quadrilateral is a four sided figure. A square has four congruent sides, hence all squares are quadrilaterals. A rectangle is a four sided rhombus, so it is also a quadrilateral.
