<p>What’s the diff btw a vertex adn an edge! I tried looking it up at google but no help! thank you :)</p>

2

<p>An edge is the side of a shape.</p>

<p>A vertex is the intersection of 2 edges in a shape.</p>

<p>ie (a cube has 12 edges, and 8 vertices)</p>

3

<p>uhh haha…</p>

<p>vertexes are sharp points in a shape.
edges are sides in a shape.</p>

4

<p>no, I think faces are sides on a shape edges are intersection of two faces, vertex is anything pointy, for example a right circular cone there is a circular face and a conical one, an edge running around the circle and one vertex on the top.</p>

5

<p>could you specify the example where you’ve seen it, or something?</p>

6

<p>oh crap, yeah i’m wrong.</p>

<p>in my head i was visualizing a 2d octagon, where edges are faces. forgot that they mean different things in 3d shapes…</p>
