Vertically opposite angles!
When two lines intersect, the angles across from each other are called vertically opposite angles, or just opposite angles. Opposite angles are equal to one another. See 'related links' below.
The angles opposite one another at the intersection of two lines are called vertical angles. Vertical angles are always equal in measure, meaning that if one angle measures 40 degrees, the angle directly opposite it will also measure 40 degrees. This property is a result of the way the lines intersect, creating pairs of angles that are congruent.
Adjacent angles
Adjacent angles are simply two angles that are next to one another and share one side. There is nothing else unique about these angles, and they are measured as one would measure any other angles.
Angles do not normally intersect one another, although coterminus angles may be said to.

The colors directly across from each other on the coor wheel are called complimentary colors.
I have never come across the phrase "parallel angles". Please elaborate.
Adjacent angles
Next to one another
A shape that has 2 pairs of equal sides and no right angles is a kite or a parallelogram. In a parallelogram, each side is equal to the one directly opposite; in a kite, the equal sides are adjacent to one another.

The triangles are similar.
Two exterior angles are consecutive if they are formed at vertices which are next to one another.
They follow one another such as consecutive or coresponding angles
It has one pair of opposite angles that are equal but not two.
