\n Let's say you are given two lines: AB & CD.
\n If both of these lines sit on the same plane and always maintain\r\n a constant distance from each other, then the two lines are said to be parallel to each other.\r\n
\r\n Mathematically, two lines that are parallel to each other are denoted as: AB || CD.\r\n
\r\n Parallel lines never intersect with each other.\r\n
\n Imagine a line that intersects a set of parallel lines. Such a line is called a\r\n transversal.
\r\n The angles between transversal and a set of parallel lines can be grouped into pairs\r\n and such pairs have special names — as we have discussed in the next section.\n
\r\n Below are the names given to pair of angles.\r\n
\n In this MagicGraph, we demonstrate an important theorem related to a pair parallel lines intersected by a transversal.\r\n This theorem states — \r\n If two parallel lines are cut by a transversal,\r\n the alternate interior angles are equal.\r\n \r\n
\r\n The blue line is a line connecting points X and Y. Point X can be moved along x-axis only\r\n while point Y can be moved along y-axis only.\r\n
\r\n The red line is a line that runs parallel to the blue line and passes through point P.\r\n Point P can also be moved around.\r\n
\r\n The dotted green line is a transversal that intersects the blue and red lines at points X and P, respectively.\r\n\r\n The angles α and β are alternate interior angles made by the transveral.\r\n
You can repeat the above steps any number of times to learn different scenarios.
