Get Proportional Segments Between Parallel Lines

Theorem (Proportional Segments): A line parallel to one side of a triangle that intersects the other two sides in distinct points divides those two sides into proportional segments.

In the Triangle Proportionality Theorem , we have seen that parallel lines cut the sides of a triangle into proportional parts. Similarly, three or more parallel lines also separate transversals into proportional parts.

When a line is drawn parallel to one side in a triangle, two similar triangles are formed because corresponding angles yield the AA similarity shortcut. Because the triangles are similar, the segments formed by the parallel line are proportional segments.

You will create segments that are proportional to each other.

If three parallel lines intersect two transversals, then they divide the transversals proportionally. If a ray bisects an angle of a triangle, then it divides the opposite side into segments whose lengths are proportional to the lengths of the other two sides.

To see whether or not two lines are parallel, we must compare their slopes. Two lines are parallel if and only if their slopes are equal. The line 2x – 3y = 4 is in standard form. In general, a line in the form Ax + By = C has a slope of –A/B; therefore, the slope of line q must be –2/–3 = 2/3.
