It is called a vertex.
a vercitie is a corner of a 3d shape such as a cube or a cuboid
A 12 sided 3D shape is a dodecahedron.
A tridekahedron is a 3D 30 sided shape.
A shape that has one corner is a cone.
Any polyhedron.
Possibly a cone
The question is not particularly clear but I suspect that the answer is a vertex.
is it a vertex
Cuboid would be an example.
sides are the face of a 3d shape and verticies are the corner of the shape

A vertex (plural: vertices or vertexes) is the point of intersection of lines (like the 'corners' of a 3D shape). A corner is the same but where only two lines are intersecting.
They are called a Vertices and it is where 2 edges meet.
A right angle.
rectangle. * * * * * Since a rectangle is NOT a 3-D shape, the answer is clearly wrong. Many 3-d shapes have a corner.
