Question

,Write a paragraph proof of this theorem: In a plane, if two lines are perpendicular to the same line, then they are parallel to each other.

Answer 1

If you understand how to write the proof the "meat" behind it is that lets say you have 3 lines: the slope of the main line is x and if a line is perpendicular to it, its slope is the opposite reciprocal which is -1/x, so if two lines are perpendicular to that line then both their slopes are -1/x and if two lines have the same slop they are parallel.

Answer 2

A being the main line and b, c being the two perpendicular lines
