WebThe intersecting lines either form a pair of acute angles and a pair of obtuse angles, or the intersecting lines form four right angles. When the lines meet to form four right angles, the lines are perpendicular. The main fact to establish about perpendicular lines has to do with uniqueness. Remember that that the midpoint of a line segment and ... Probably the best-known equivalent of Euclid's parallel postulate, contingent on his other postulates, is Playfair's axiom, named after the Scottish mathematician John Playfair, which states: In a plane, given a line and a point not on it, at most one line parallel to the given line can be drawn through the point. This axiom by itself is not logically equivalent to the Euclidean parallel postulate since there are g…

WebApr 11, 2024 · It cannot be possible that two lines are intersecting at two points. Note: Here you should know the difference between intersecting lines and parallel lines. Intersecting lines are lines that, at some point, cross or meet. Parallel lines, where two or more lines lie in the same plane and never intersect, are parallel. WebJan 17, 2024 · The line is the one-dimensional figure, which has only length, not width. According to Euclid’s second postulate, the line is a breadthless figure. A line has infinite points on it. The line extends infinitely in both directions. The length of the line is not fixed, as it has infinite length.
