Yes (supposing that by side you mean ray...angles don't have sides because they are 2D, not 3D.) If you have a point and you draw four random rays from that point, that only meat at that point, then you would have created four angles. The two angles on opposite sides of the point will share a vertex, but not a RAY.
Adjecent Angles
Adjacent angles share a vertex and one ray, while any two angles that don't share both those things are nonadjacent.
Two angles that share a common side and add up to 180 degrees are called right angles and are 90 degrees.
opposite angles
a bite me.
Adjacent angles share a ray.
adjacent

It requires the common ray of the two angles to bisect the combined angle.
complementary angles
Adjecent Angles
If they share a ray, then they are basically combined together and since complementary angles add up to 90 degree angles a right angle is formed.
They are adjacent angles.
No
Adjacent angles.
The complementary angles form a right angle with the shared ray.
