Pairs of Angles. When parallel lines get crossed by another line (which is called a Transversal ), you can see that many angles are the same, as in this example: These angles can be made into pairs of angles which have special names. Click on each name to see it highlighted: Now play with it here.

180^o 180o: Sometimes called ‘C ‘C angles’. What are angles in parallel lines? Key angle facts. To explore angles in parallel lines we will need to use some key angle facts. Angles on a straight line. x+y=180^o x + y = 180o. (The sum of angles on a straight line equals 180^o 180o) Angles around a point. e+f+g+h=360^o e + f + g + h = 360o.
Parallel lines are lines in the same plane that go in the same direction and never intersect. When a third line, called a transversal, crosses these parallel lines, it creates angles. Some angles are equal, like vertical angles (opposite angles) and corresponding angles (same position at each intersection). Created by Sal Khan.
Video transcript. Let's do a couple of examples dealing with angles between parallel lines and transversals. So let's say that these two lines are a parallel, so I can a label them as being parallel. That tells us that they will never intersect; that they're sitting in the same plane.
If parallel lines are cut by a transversal (a third line not parallel to the others), then they are corresponding angles and they are equal, sketch on the left side above. We know that angle x is corresponding to angle y and that l || m [lines are parallel--they told us], so the measure of angle x must equal the measure of angle y.
When the lines are parallel, the measures are equal. ∠1 and ∠2 are alternate interior angles. ∠3 and ∠4 are alternate interior angles. Alternate interior angles are " interior " (between the parallel lines), and they " alternate " sides of the transversal. Notice that they are not adjacent angles (next to one another sharing a vertex).
