Quick answer needed! Is a vertice - vertex?? - on a 3d shape where two edges meet?

And what are the areas where a few of them meet ie. a corner?

Thick emoticon needed.

vertices are the edges. will go and ask ds what the corners are called blush

it is a corner, or at least that is what I thought

corner sounds too un-mathematical though!

Vertices are corners of 3D shapes. Edges are edges!

Vertices are also corners of 2D shapes.

Apex? Zenith?

Vertices are the points where 3 or more faces meet. Where two meet, it's an edge. This page might be helpful in explaining the naming of parts in a polyhedron.

From Dictionary.com

Vertices (singular = vertex) are the sharp bits on a solid shape! Also known as the corners. Edges are the "lines." Faces are the flat bits - where the dots are an a die, for instance.

Got it, thanks all! Asked the 10 year-old.
