The participants use different types of angles (e.g. linear pairs,...).

1. which of the following points is the best defining of a linear pair of vertices? 1 point

A linear pair is a pair of brackets whose dimensions add up to 180 degree and divide a com.

None of the options I would consider as a valid linear pair defining. a) -- Not enough, because the joint beam could be the "initial side" of both angle. In order to complement this description, it must be said that the two corners have no inner points in common. However, the two corners have no inner points in common. Therefore, the two corners have no inner points in common. What is more, they have no inner points in common. What is more, they have no inner points in common? b ) -- Not enough, since this does not mean that the angle must divide a beam.

Not enough. In the case of two crossing lineages, the angle in a linear pair will have sides that are opposite beams; but the perpendicular angle created by the two crossing lineages will also have sides that are opposite beams. Every linear pair has one side pair that are opposite beams; every perpendicular pair has two side pair that are opposite beams.

You could correct this by saying that the angle pair has only one side pair opposite the beams, but that makes a very unpleasant one. d ) -- Not enough, since it says nothing about the total of the 180-degree angle. Best of luck in selecting the "best" of the four inadequate definitions.

An easy way to define it is to say that the angle is side by side and complementary. Neighboring " cares about the joint beam and no points, supplementing " about the total of 180 degree.
