Parallel line theorem, there is a better way? Now I don't need to talk about the judgment theorem of the first day of junior high school. It's in the textbook. Now I find a new theorem. What do you think. Two parallel lines, take a midpoint, and the line rotates around the midpoint. For example, the horizontal line becomes a vertical line. The second line rotates by the same degree. If the distance between the two lines is still equal, then the two lines are parallel. May I write a paper?

This is wrong in itself

Is the determination of parallel line in grade one mathematics a theorem or a basic fact?

Which judgment method do you mean
Except that the parallel axiom is a basic fact, the rest are theorems

Judgement axiom of parallel line judgement theorem of parallel line 1 judgement theorem of parallel line 2

The two lines are parallel
The internal stagger angles are equal and the two lines are parallel
The inner angles of the same side complement each other, and the two lines are parallel

What is the determination theorem of parallel lines
Please talk about it concisely and without missing any knowledge

The judging theorem of parallel line: (1) two straight lines are cut by the third straight line, if the same position angle is equal, then the two straight lines are parallel; (2) two straight lines are cut by the third straight line, if the internal stagger angle is equal, then the two straight lines are parallel; (3) two straight lines are cut by the third straight line, if the internal angles of the same side are complementary, Then the two lines are parallel. (4) if the two lines are parallel to the third line, then the two lines are parallel to each other (transitivity of parallel lines)
