When any two parallel lines are intersected by another line called a transversal, many pairs of angles are formed. While some angles are congruent (equal), the others are supplementary. Observe the following figure to seeparallel lines cut by a transversal. The parallel lines are labeled as L1...
Parallel Lines and Transversal Applet What is a transversal? Answer: A transversal is a line, like the red one below, that intersects two other lines. Typically, the intercepted lines like line a and line b shown above above are parallel, but they do not have to be. What is so ...

If two parallel lines are cut by a transversal, the corresponding angles are congruent. The converse of this theorem is the following. If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel. The converse of the corresponding angles theorem is ...
Theorem 17:If two parallel lines are cut by a transversal, then every pair of angles formed are either equal or supplementary. Theorem 18:If a transversal is perpendicular to one of two parallel lines, then it is also perpendicular to the other line. ...
2. The alternate angles are equal 3. The sum of the interior angles on the same side of the transversal is \({180^ \circ }\) In the given diagram, if \(AB\parallel CD\) and \(TS\) is a transversal, then, Properties of Parallel Lines Cut by a Transversal ...
If two lines are cut by a transversal such that the corresponding angles are congruent then the lines are parallel. What is the alternate interior angles theorem? If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent. ...
Parallel Lines: In geometry, two coplanar lines are parallel if they never meet each other and always maintain the same perpendicular distance between themselves. For parallel lines cut by a transversal, the alternate angles are equal. The corresponding angles also have equal measures. ...
mostly biconditional statements. For example, according to one theorem, when a transversal crosses two parallel lines, they form equal alternating interior angles. So, its converse, that is, the lines cut by a transversal are parallel if the alternate interior angles formed are equal, is also ...
