less than and right angles
complemtary
They would be called intersecting lines.Intersecting lines form Vertically Opposite Angles. Each pair of opposite angles (sharing only a vertex) is congruent. Each of the four pairs of adjacent (sharing a side) angles forms a straight angle (they add to 180o).
Nonadjacent angles formed by two intersecting lines are pairs of angles that do not share a common vertex or side. When two lines intersect, they create four angles, and the angles that are opposite each other are called vertical angles, which are nonadjacent. For example, if two lines intersect, the angles formed at the intersection can be labeled as angles 1, 2, 3, and 4; angles 1 and 3, as well as angles 2 and 4, are nonadjacent to each other.
In mathematics, particularly in geometry, "vertically opposite" refers to pairs of angles that are formed when two lines intersect. These angles are opposite each other and are always equal in measure. For example, if two lines cross, the angles formed at the intersection can be categorized into pairs of vertically opposite angles, which share a common vertex but do not share a common side.
They're the 'base angles'.

They are said to be perpendicular. Or, if you wanted an example of a pair of such lines, one example is a plus sign.

Coterminal angles are angles that are formed at the same vertex.

I don't know but i think they're intersecting. :D
opposite angles
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.
