triangle
Many 3d shapes have a corner.
A shape with one corner is a triangle. Yes, I know, technically it has three sides, but it only has one corner. So, there you have it, a triangle is the shape you're looking for.
Wich 3 D shape has a corner on it?
A teardrop shape?
A diagonal.
The corner on a shape where edges meet is called a vertex.
Any polyhedron.
Possibly a cone
rectangle. * * * * * Since a rectangle is NOT a 3-D shape, the answer is clearly wrong. Many 3-d shapes have a corner.
a ertex
a square
The corner of a 2D shape is called a "vertex" (plural: vertices). A vertex is a point where two or more edges meet, and it is a fundamental element in defining the shape's structure. In polygons, each vertex corresponds to a corner of the shape.
