Webb13 dec. 2024 · If two lines are cut by a transversal so that any pair of corresponding angles are congruent, then the lines are parallel. You can use these converses to decide whether two lines are parallel. Example 1A mosaic designer is using quadrilateral-shaped colored tiles to make an ornamental design. Each tile is congruent to the one shown here. WebbAnd in particular, it's at a right angle. And if you have two lines that intersect a third line at the same angle-- so these are actually called corresponding angles and they're the same-- if you have two of these corresponding angles the same, then these two lines are parallel. So line ST is parallel to line UV. And we can write it like this.
