can parallel lines intesect?

Theorytical if the line are formed on a flat gemetrical plane they will not intersect.Or if two tangent in a in the same circle are parallel they will never intersect.\nThe fith postulate of Euclid tackled this question.Later mathematicians, like gauss proved that they could intersect. But this proof was based on a different idea=paralell line having curvatures! Of course they would intersect. So the geometry which based on curvatures was started and was called Non Euclid Geometry.\nActually this could have been proven alot fast with some common sense! In reality it is imposible to construct a perfect circle or a perfect straight line(this is my own postulate).   This is because we are not able to have a perfect resolution of measurement.\nNot matter how you try to measure two parallel line  the results is ether convergence or divergence of the two lines if you make the line long enough!So in practice the 5th postulate of Euclid did have a practical application.

No. The diagonals of a parallelogram bisect each other, but they don't bisect the angles.

if all the lines are equal in every way (duplicate) then you can put a measurment (dimension) from the existing line to a datum or border whichever you choose and then put a callout like 3@12.00' (3 lines at 12.00 feet)in the dimensionwith a arrow pointing at the line.\n\njeff

if they're perpendicular, then they have to intersect at some time. Now if they were parallel, they would never touch

If there are Colours Join the Colors same to the same... Like I mean join the same colors... together...\n\nok.. i actually have no idea..\n\nMaybe it would help..

Angles that are formed when parallel lines have a common intersecting line  (this intersecting line referred to as a transversal) Corresponding angles formed will have the same measure,alternate exterior angles formed, as well asalternate interior angles formed by the same transversal shall also be of the same measure. draw two parallel lines cross them both with a tranverse line at 45 degrees and you will be amased that all the corresponding angles will be 45 degrees. Simply mind bogling isn't it.

If you mean parallel to y=2x + 5, then the slope will be 2\n\nSo you need to use:\ny = 2x + b\n\nPlug in your point (-1, 4) and solve for b:\n4 = 2(-1) + b\n4 = -2 + b\nb = 6\n\nSo your line is:\ny = 2x + 6

Parallel is parallel.....it's like being a 'little' pregnant....either you ARE or you are NOT.\n\nYes, they are parallel to the 3rd line.

Imagine three lines converging on a single point. The angle between line 1 and line 2 is adjacent to the angle between line 2 and line 3. See the diagram in the Wikipedia article linked below.

No.\nA straight line is obtained by joining two distinct 'points'.\non this line there lies infinite 'points' between the given end-points.\nSo, a strsaight line is actually a set of POINTS.

the y coordinates are the same i.e. -1, \nso the line is parallel to the x axis and passes through -1 on the y axis.\nits slope is parallel to the x axis.

More completely, given two lines ax1 + bx2 = c and dx1 + ex2 = f, they can either intersect completely, in which case the solution set is a line, or they can intersect in one point, or they can not intersect at all (parallel lines). This is due to Euclidean geometry.\nIf you're more of an algebraist, suppose they intersected at more than one point (x1, x2) and (y1, y2). Then ax1 + bx2 = ay1 + by2 and dx1 + ex2 = dy1 + ey2. But then (a-d)x1 + (b-e)x2 = (a-d)y1 + (b-e)y2, so (d-a)/(b-e) = (y2-x2)/(y1-x1). Suppose we chose another point (z1, z2) on the line formed by (y1, y2) and (x1, x2). But note that (z1, z2) will also satisfy the equations, hence the entire line satisfies the equations whenever more than one point satisfies the equation. This is just the first case given above (the lines completely overlap). \nNote the degenerate condition (x1,x2)=(y1,y2) of a single solution gives an undefined quotient 0/0.

in small scale your horizontal line would be a straight ;line however if it is in large scale your horizontal line would bend

No, because the charges will have to distribute to opposite sides of the strip (as if it was a loop rather than a mobius strip), however since we are dealing with a one dimensional object (essentially), the charges cannot do this.

Lines which lie in the same plane and never intersect.

The previous answers are either wrong/incomplete/mischievious.\nFirstly there is nothing called parallel angles! You probably meant to ask what happens if the angles of two triangles are same. In that case there is no congruence/similarity between the two triangles.\nBut if two angles are equal betwen them, they are SIMILAR (same shape) and not congruent.\nIf in addition they have a side equal, they become congruent!
