In Geometry, when any two parallel lines are cut by a transversal, many pairs of angles are formed. There is a relationship that exists between these pairs of angles. While some of them are congruent, the others are supplementary. Let us learn more about the angles formed when parallel line...

In geometry, lines are of infinite length. So, yes, parallel lines have the same length. They are completely 'G' rated at all times. They never touch. Is a rectangle and a parallelogram the same? A rectangle is a type of parallelogram. A parallelogram by nature is a geometric...
You can also use similar triangles to show that two lines are parallel. For example, suppose that ΔADE ~ ΔABC in Figure 14.5. You can prove that ¯DE ¯BC. Example 2: If ΔADE ~ ΔABC as shown in Figure 14.5, prove that ¯DE ¯BC. ...
Parallel Lines In geometry, parallel lines are lines in a plane which do not meet. This definition appears asDefinition 23 in Book I of Euclid's Elements.
