A straight line which is not vertical.
Linear has a slope direct does not but both go through the orgin
A good theme would be space, such as angles on stars. Another one would be a sport, like tennis. For angles you could use the angles of arms with people playing.
In the sense of an adjectival form fro a line, there is no difference, except that lineal is an older version. In the context of genealogy - ancestors and descendants - lineal is used rather than linear.
No, in fact, vertical angles can't be a linear pair. Vertical angles are opposite from each other which also make them equal each other. A linear pair has two angles adjacent to each other that eqaul 180 degrees.
A linear pair would be two angles that form a straight angle of 180 degrees.
no it's impossible
you bet it can
Yes, they can.
Supplementary angles do not have to be next to one another but, they can be parts of two different shapes.

vertical angles theorem
linear
distinguish between linear and non linear demands funcions
No. All linear pair angles are supplementary, but supplementary angles do not have to be a linear pair.
