When constructing parallel lines, how can you be sure the lines you constructed are parallel?

See if the distance between the two lines is consistent with a compass.

Make sure the lines intersect at right angles with the corner of a piece of paper.

Measure each of the angles with a straightedge.

There is no way to ensure you have constructed parallel lines.

wats ur guess ? :)

ganeshie8 · Answer

maybe start by eliminating options that make no sense to you

lauluisa · Answer

I think is either B or C

ganeshie8 · Answer

you dont measure ANGLE  wid a STRAIGHT EDGE

ganeshie8 · Answer

clearly last option also u can strike off
so C and D are gone.

answer is between A and B

This page shows how to construct a line parallel to a given line that passes through a given point with compass and straightedge or ruler. It is called the 'angle copy method' because it works by using the fact that a transverse line drawn across two parallel lines creates pairs of equal corresponding angles. It uses this in reverse - by creating two equal corresponding angles, it can create the parallel lines
