Practice Parallel Lines And Transversals If two lines are parallel then the interior angles on the same side of the transversal are supplementary (they add up to \(180^{\circ}\)). if the interior angles of two lines on the same side of the transversal are supplementary then the lines must be parallel. The transversals of b d ↔ are a b ↔ and c d ↔. 6. calculate: m ∠ 1 = 70 °. solution: ∠ 1 ≅ ∠ 4 m ∠ 4 = 70 °. ∠ 1 ∠ 2 m ∠ 2 = 180 ° − 70 ° = 110 °. m ∠ 3 = 110 °. in this section, we’ll be discussing the properties of parallel lines and transversals. parallel lines are lines on the same plane that never intersect. Theorem: if two or more parallel lines are cut by two transversals, then they divide the transversals proportionally. figure \(\pageindex{1}\) if \(l\parallel m\parallel n\), then \(\dfrac{a}{b}=\dfrac{c}{d}\) or \(\dfrac{a}{c}=\dfrac{b}{d}\). note that this theorem works for any number of parallel lines with any number of transversals. when.

In chapter 1 we defined a transversal to be a line which intersects two other lines, we will now extend the definition to a line which intersects three other lines. in figure \(\pageindex{1}\), \(ab\) is a transversal to three lines. figure \(\pageindex{1}\): \(ab\) is a transversal to three lines. A transversal is a line that crosses at least two other lines. the red line is the transversal in each example: transversal crossing two lines. this transversal crosses two parallel lines.
