what does a vertex look like
A bow-tie type connection of 2 triangles.
look for the interceptions add these and divide it by 2 (that's the x vertex) for the yvertex you just have to fill in the x(vertex) however you can also use the formula -(b/2a)
It looks like four equilateral triangles that have been put together so that one vertex of each meet at a point.

A vertex !
a dot
It looks like an isoceles triangle that has had its vertex cut off parallel to its base.
Six points.

A non convex polygon would have an exterior angle less than 90 degrees making it look concave at that vertex.
A chevron. Basically, any polygon with an acute angle whose vertex points to the center of the shape.

That's a "central angle", but the part that really fascinates me is this: What would it look like if you hadan angle whose vertex was in the center of the circle and whose sides didn't intersect ? ? ?

The vertex is not affected by the direction that the parabola is facing. The vertex is the place where the two sides of the parabola meet. It is in the middle divides the shape in half. If you picture yourself looking at a bowl from the side and then imagining it as two dimensional, it would look like a parabola but for all of the filled in parts of the graph and the fact that the sides of the bowl don't continue on forever. The vertex is the bottom of the bowl, where the sides meet. You measure a vertex as you would a point; with a coordinate.
