I believe VOR works in the following manner.
On one frequency a beacon goes out in all directions. That starts a
clock in the vor instrument in the airplane. Meanwhile a rotating beacon
on another frequency broadcast from the same vor hat on the ground
broadcasts starting in the due north 0 radial direction and spinning
around.
Because it takes a known amount of time to go around 360 degrees, you
know which radial you are on by the difference in time between the first
beacon and when the rotating beacon hits you in your position in the
airplane. The later it hits you, the higher radial around.
While the vor itself doesn't use triangulation, pilots can use two or
more vor's to triangulate their position.
By tuning and learning the radial of two different vor's you know you
are on the intersection point of those two radial lines above the
ground.

I understand what is VOR
(with triangulation based on 2 frequencies), but fail to find some
VOR does not use triangulation ... it uses a a reference radio
signal and another out of phase to indicate azimuth from the station.
You can use DME or time * distance to calculate distance from the VOR.
google for "VOR navigation" for a plethora of tutorials.
Also, the simpler the navigation aid, the more work to navigate.
After the VOR, you may want to learn the ADF.
