They are called adjacent angles.
adjacent
If they are in the same plane, then they share a common plane. Did you mean to say common point. If that's the case where they are in the same plane, but do not share a common point, then they are parallel lines.
isosceles triangle
Yes, and a common side too.

Adjacent angles
A shape with a circular base and a vertex that isn't in the same plane as the base is called a cone.
The Common Vertex is the place where multiple vertices meet in the same spot on their vertices.
