Are parallel lines equal to each other?
Consequently, are parallel lines equal?
are equal in measure. If two parallel lines are cut by a transversal, the alternate exterior angles are congruent. If two lines are cut by a transversal and the alternate exterior angles are congruent, the lines are parallel.
Secondly, which lines are parallel to each other? In other words, the slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other. Here is a quick review of the slope/intercept form of a line.
Also to know, are parallel lines equal in length?
The angles that fall on the same sides of a transversal and between the parallels (called corresponding angles) are equal. The two parallels lines are a constant distance apart, so any pair of lines that intersects them at the same angle will make segments with the same length.
What are parallel lines and Transversals?
Parallel Lines & Transversals. A transversal is a line, or line segment, that intersects two or more other lines, or line segments. When a transversal intersects parallel lines, many angles are congruent.
