A pyramid is a four-sided 3D triangle
A 12 sided 3D shape is a dodecahedron.
A tridekahedron is a 3D 30 sided shape.
No. A three-sided polygon is, by definition, a triangle.
they are: ---sided pyramids and triangular prisms and 20 sided 3d shapes
A five sided 3d shape is called a pentehedron
A pyramid is a four-sided 3D triangle
There is no name for a five sided regular polygon. A five sided polyhedron is called a pentahedron.
A triangle by definition only has 3 sides, so a 5-sided triangle does not exist - unless you are including the in-side and out-side of it as two more sides. A five sided polygon is a pentagon.
A 3D 5 sided shape is called a dodecahedron. It is a solid with 20 vertices, 30 edges and 12 equal pentagonal triangular faces.
It has 5 corners if it is a 3D shape like a piramid but if it is 2D it is 3
Pentagon 2d shape is a pentagon 3d object is a pyramid.
A 12 sided 3D shape is a dodecahedron.
A tridekahedron is a 3D 30 sided shape.
An 11-sided 3D shape is a hendecahedron.
There is no such thing as a 3D triangle.
A 12 sided 3D shape is called a dodecahedron.
