What are three biconditionals about parallel lines and transversals?
Three biconditionals regarding parallel lines and transversals are: If two lines are parallel, then corresponding angles formed by a transversal are congruent. If a transversal intersects two lines such that alternate interior angles are congruent, then the lines are parallel. If two lines are cut by a transversal and the same-side interior angles are supplementary, then the lines are parallel.
Two lines parallel to the same plane are parallel to each other?
they are transversals to each others
Where do two distinct parallel lines intersect?
A vertex? In non-euclidean geometry: A two distinct parallel lines intersect in the "Infinity zone"
How many points can 2 distinct lines intersect?
Two distinct lines can intersect at most at one point. If the lines are not parallel, they will cross at a single point. If they are parallel, they will never intersect. Therefore, the maximum number of intersection points for two distinct lines is one.
Is it true if a transversal is perpendicular to one of two parallel lines then it is perpendicular to the other?
Yes, it is true. If a transversal is perpendicular to one of two parallel lines, it must also be perpendicular to the other parallel line. This is a consequence of the properties of parallel lines and transversals, which dictate that corresponding angles formed by the transversal and the parallel lines are congruent. Therefore, if one angle is a right angle, the other must also be a right angle, confirming the perpendicularity.

Two lines parallel to the same plane are parallel to each other?
they are transversals to each others
Can transversals be parallel to each other?
Sure. You could have a set of parallel lines crossed by two transversals that are parallel to each other. The figure formed by their intersection would be a parallelogram! That's one way of looking at it...
Lines m and n are parallel if lines m and n are cut by three different transversals which also what is the least number of points of intersection that can occur among five lines?
four

Two distinct lines that do not intersect are parallel?
2 lines the same width apart are parallel.

What is the intersection of two distinct line?
The intersection of two distinct lines occurs at a single point if the lines are not parallel. This point is where the lines meet or cross each other in a two-dimensional plane. If the lines are parallel, they do not intersect at any point, and if they are coincident, they overlap completely but are not considered distinct.
What are the angle relationships formed when a third line intersects two parallel lines?
When a third line intersects two parallel lines, several angle relationships are formed. Corresponding angles are equal, alternating interior angles are equal, and consecutive interior angles are supplementary (adding up to 180 degrees). These relationships are crucial in understanding the properties of parallel lines and transversals in geometry.
If two distinct lines intersect?
Then they are not parallel, nor skew (in 3D).
How many parallel lines are there in a octagon?
In a regular octagon, there can be multiple sets of parallel lines. Specifically, each pair of opposite sides of the octagon is parallel to each other. Since an octagon has 8 sides, there are 4 pairs of parallel lines, resulting in a total of 4 distinct sets of parallel lines.
