Where do two distinct parallel lines intersect?
A vertex? In non-euclidean geometry: A two distinct parallel lines intersect in the "Infinity zone"
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.
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.
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.

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.
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.
If two distinct lines intersect?
Then they are not parallel, nor skew (in 3D).
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).

How many parallel lines on hexagon?
A hexagon can have multiple pairs of parallel lines depending on its orientation. In a regular hexagon, there are three pairs of opposite sides that are parallel to each other. Therefore, there are a total of three distinct pairs of parallel lines in a regular hexagon.
What patterns do you observe among the angle measures?
There are different patterns in different circumstances: for example when two (or more) parallel lines are intersected by one (or more) transversals; or when considering the interior or exterior angles of polygons.
How many parallel lines in square?
A square has four sides, and each pair of opposite sides is parallel to each other. Therefore, there are two pairs of parallel lines in a square. In total, this means there are two distinct sets of parallel lines, resulting in four parallel lines if you count both sides of each pair.
