less than and right angles
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).
They're the 'base angles'.
I don't know but i think they're intersecting. :D

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.

opposite angles
Vertex angle
Vertically opposite angles are the angles that are opposite each other when two lines cross. Vertical means they share the same vertex.
The angles that share a vertex and a side of a transversal but no interior points are called vertical angles. Vertical angles are formed when two lines intersect, and they are always congruent.
The top and bottom angles - the angles that are between the pairs of congruent sides. They are opposite each other and not necessarily congruent.
