The common vertex between two points
To measure an angle you must take all the points in between the two. Therefor it could be anywhere from 2 to 100 points.
Only if the are angle between two rays or an angle caused by three points. Both angle would also have to be exactly 45 degrees.
Point common to two sides of an angle = vertex. Points common to two sides of a polygon, if they exist, are all the points along an edge.
