sides are the face of a 3d shape and verticies are the corner of the shape
A right angle.
A 3D semi circle
A cone.
2D shape = Decagon 3D shape = Decahedron
Many 3d shapes have a corner.
Possibly a cone
Any polyhedron.
is it a vertex
The question is not particularly clear but I suspect that the answer is a vertex.
Cuboid would be an example.
sides are the face of a 3d shape and verticies are the corner of the shape
It is called a vertex.
a vercitie is a corner of a 3d shape such as a cube or a cuboid
I just want to say that no 3D shape has corners, they have vertices (singular vertex), which is what you might call a corner, but this is the correct terminology.A sphere has no corners (as it is 3D), but it also has no vertices.
They are called a Vertices and it is where 2 edges meet.
A right angle.
