They are called adjacent angles.
adjacent
Angles in the same plane that have a common vertex and a common side are called adjacent angles. These angles share one side and the vertex where they meet, but they do not overlap. Adjacent angles can be formed by two rays emanating from a common point, and their measures can be added together to find the angle formed by the entire rotation around the vertex.
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.

pyramid and coneIn the list given, only the cone and pyramid have a vertex.
isosceles triangle
Yes, and a common side too.
