In 2D geometry, that is the definition of parallel lines. Two non-intersecting lines are indeed parallel.

3 ways that 2 lines can be related?
Here are some: They can be (1) coincident, (2) intersecting at one point, (3) coplanar but non-intersecting (ie parallel), (4) non-coplanar, non-parallel and non-intersecting (eg paths of a rail line and of an elevated road going over it - from above, they may appear to intersect but they do not), (5) intersecting at two points (eg longitudes on the earth). etc.
What has 2 acute and 2 obtuse angles?
A rhombus, two sets of parallel lines intersecting,
Does a square have intersecting lines?
Yes, squares do have intersecting lines. Infact they have 2 diagnol intersecting lines.
Will non parallel lines intersect?
If the 2 lines lie in the same plane, and they are not parallel, then they will intersect at some point. If the 2 lines are skew lines, then they are not in the same plane, and they will not intersect (but they are Not Parallel)
What is a pair of angles formed by two lines intersected by a third line?
More info needed. Are the 2 lines parallel, perpendicular, or? are the angles that you are interested in on opposite sides of the intersecting line or the same side. The intersecting line is called a transversal. If the original lines are parallel, angles between the 2 lines on opposite sides of the transversal are called alternate interior angles, etc.
What are 2 non perpendicular intersecting line called?
Intersecting Lines

How many parallel lines does a arrow head have?
2. actually, none, the lines are intersecting
What has 2 acute and 2 obtuse angles?
A rhombus, two sets of parallel lines intersecting,
What figure has parallel diagonals?
Parallelograms have parallel diagonals (these include squares, rectangles, rhombi, an trapezoids). Parallel lines are lines with the same slope that could carry on infinitely without intersecting. A parallelogram can have 1 or 2 sets of parallel lines.

Yes, squares do have intersecting lines. Infact they have 2 diagnol intersecting lines.
Will non parallel lines intersect?

Can a triangle have 2 parallel lines?
A triangle has by definition three intersecting sides. If two of the sides are parallel, they will never intersect, so no triangle can ever be formed.
What is a pair of angles formed by two lines intersected by a third line?
More info needed. Are the 2 lines parallel, perpendicular, or? are the angles that you are interested in on opposite sides of the intersecting line or the same side. The intersecting line is called a transversal. If the original lines are parallel, angles between the 2 lines on opposite sides of the transversal are called alternate interior angles, etc.
Kinds of straight lines?
skew, parallel, intersecting.
Types of intersecting lines?
as long as there is 2-infinite amount of lines meeting at one point, (intersecting) it is known as an intersecting line.
Can a system of 2 linear equations have exactly 2 soltions?
No. There are none, one or infinitely many solutions. No other value is possible. A system of two linear equation can be represented by two straight lines in space (of 2 or more dimensions). Such lines can be non-intersecting (0 solutions), or they can intersect at one point (1 solution), or they can be coincident (infinitely many solns). Two non-intersecting lines in 2-d space must be parallel but in spaces of 3 or more dimensions they can simply be non-coplanar. For example, imagine you are in a cuboid room. One line is the join of the walls to your left and behind you, the other line is where the floor meets the far wall. These lines are not parallel but they do not meet.
