Parallel lines are straight equidistant lines that lie on the same plane and never meet each other. When any two parallel lines are intersected by a line (known as thetransversal), the angles that are subsequently formed, have a relationship. The various pairs of angles that are formed on t...
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 used to prove two lines are parallel if a pair of corresponding angles are known to be congruent. For example, look at the following ...
We can say that a line is parallel to another line if they have equal distance from each other. Download Parallel and Perpendicular Lines (Songkran Festival Themed) Math Worksheets This is a fantastic bundle which includes everything you need to know about Parallel and Perpendicular Lines across...
Theorem 14.2: If a line is parallel to one side of a triangle and intersects the other two sides, then it divides these sides proportionally. Example 1: Write a formal proof of Theorem 14.2. Solution: This theorem is illustrated in Figure 14.4. ...
Example 1Are the two lines cut by the transversal line parallel? What property can you use to justify your answer? SolutionWe have been given a figure where two lines have been cut by a transversal. We need to confirm whether the given lines are parallel. Let us observe the angles marked...
Thetransversal lineis defined as ” A line which intersects two or more lines at distinct points”. For example Fig -1 :Here lines‘ n’ & ‘ m’are parallel lines and a line ‘l’intersection both lines at distinct points so a line ‘ l’ is atransversalto given lines of ‘n’ an...

finding the Helly number for line transversals to a family of parallel triangles in the plane: (1) If each three triangles of a family of parallel right triangles are intersected by an ascending (or a descending) line, then there is an ascending (or a descending) line that intersects all...
Theorem 3.4-1 Perpendicular Transversal Theorem Theorem In a plane, let two parallel lines be cut by a transversal. If the transversal is perpendicular to one of the parallel lines, then it is perpendicular to the other parallel line. If… Then… Copyright © 2014 Pearson Education, Inc. Th...
When two lines or two planes intersect, it means they cross each other in some way. Both lines and planes are perfectly straight or flat. This means that intersecting lines meet at a single point while intersecting planes form a single, straight line where they intersect....
