Equilateral triangles, squares, regular pentagons.
A rectangular pyramid has five faces. Sides are the same things as faces. A pyramid with a triangular base has 4 faces. This is the more common type of pyramid in mathematics, as it is a platonic solid.
Yes. A triangle is a type of polygon and it has NO parallel sides!!!!!!!
Rectangles and squares are the only ones.
A polygon is a plane (2-dimensional) object bounded by straight lines. A polyhedron (not polyhendron!) is a solid (3-dimensional) object bounded by polygonal faces. So, pyramids and some prisms are polyhedra. A cylinder is a type of prism but, because two of its faces are circular, those faces are not polygons. As a result a cylinder is not a polyhedron.
A square is a type of rectangle. A rectangle is a type of polygon. Polygons are just 2D shapes with more than three straight sides, where there are no open ends or lines crossing over each other. Triangle and up, basically.
Platonic
Platonic solids are 3D shapes formed using only regular shapes. Only 1 type of regular shape is used to make a platonic solid. Platonic solids are the simplest and purest form of 3D shapes.
If the type of solid (die) is a Platonic solid, then the opposite sides add to the number of faces plus one. For example, a cube's opposite sides add to seven.
Polygons are a special type of 2-dimensional shapes.
pentagons
acctualy there are three solid liquid and gas
A rectangular pyramid has five faces. Sides are the same things as faces. A pyramid with a triangular base has 4 faces. This is the more common type of pyramid in mathematics, as it is a platonic solid.
Equilateral triangles
equilateral triangles-Apex ;)
it caves in...type it in google images
The Modern Five Platonics are ( quite different than the originals known to Plato and Kepler, are in art classes: Sphere, cube, cone, cylinder, and Pyramid. Tetrahedron is another word for the last-named solid. it was a virtual connundrum in art classes that they were basic, required material and the theory was nobody could draw in perspective without this background. Jon Gnagy among others pushed the 5 Platonic solids in his art courses on TV. of course if one is drawing monuments, it is obvious.They were the type of thing that was popular with teachers not so popular with students.
A triangle, a square, a rectangle, a pentagon are all polygons.
