Two parallel railway tracks are shown with a ladder crossing them (transversal). Angle \(\angle f\) and \(\angle d\) are formed at intersections. An engineer checks if \(\angle f = \angle d\) to confirm parallelism of the tracks. He measures \(\angle f = 134^{\circ}\).

a. Name the type of angles \(\angle f\) and \(\angle d\).
b. Find \(\angle d\) if \(\angle f = 134^{\circ}\).
c. Which property ensures that the tracks are parallel?
d. A certain angle is \(17^{\circ}\) more than its complement. Find the measure of the angle.
