There are two parallel lines in the given image: t and P
t and the line passing through points (122, 58) and (62, 122)
This can be deduced from the following information:
t and the line passing through points (122, 58) and (62, 122) form alternate interior angles with each other, which are equal (58 degrees and 62 degrees, respectively).
Parallel lines have equal alternate interior angles.
Therefore, t, the line passing through points (122, 58) and (62, 122), and P are all parallel to each other.
Alternate interior angles: Alternate interior angles are two angles that are formed on opposite sides of the transversal and inside the parallel lines. In the diagram, angles 1 and 3 are alternate interior angles.
Corresponding angles: Corresponding angles are two angles that are formed on the same side of the transversal and in the same corresponding positions relative to the parallel lines. In the diagram, angles 1 and 4 are corresponding angles.
Parallel lines have the following properties:
Parallel lines never intersect.
Alternate interior angles formed by a transversal are equal.
Corresponding angles formed by a transversal are equal.
