Triangulation of a signal such as the microwave signal from a cell phone involves the use of three receiver towers. Each tower receives the signal at a different time. Since the signal travels at the same speed, and the distance between the towers is known, its possible to calculate the location of the phone. In a simplistic sense, you take the time to reach the tower times the speed of the signal. Repeat this distance calculation for each tower. This gives you a relative distance of the phone from each tower. If you then draw a circle scaled equal to the distance around each tower on a map, the spot where the three circles overlap would be the location of the phone. More precise calculation would involve some additional corrections, but the simple sense gets you pretty darn close.
HOWEVER, since your cell phone has a unique identifier, even if someone can't tell where you are when you place a call, they can tell who (or whose phone) the call came from. Triangulation would normally be used in emergency situations since it tends to tie up time on three towers, where your phone normally tries to connect to the closest one.

Triangulation is a process by which the location of a radio transmitter can be determined by measuring either the radial distance, or the direction, of the received signal from two or three different points. Triangulation is sometimes used in cellular communications to pinpoint the geographic position of a user.

Triangulation is the process of determining a point from the angles of two or more known points. The point where the lines intersect from the known points will determine the location of the unknown point, ie, the cellphone. When a call is placed on a cell phone, the signal strength is measured by multiple receiver towers, the one with the stronger tower is used to complete the call. It is possible to triangulate the locaiton of the cell phone based on the angles received from multiple towers that surround the cell phone.

triangulation is the process of finding coordinates and distance to a point by calculating the length of one side of a triangle, given measurements of angles and sides of the triangle formed by that point and two other known reference points, using the law of sines.
In cell phone triangulation 3 towers are used. The first tower judges the distance to the caller who could be anywhere along the call circle. Distance from the 2nd tower narrows the choice of 2
points and the 3rd tower pin points the location of the caller

Quite simply, it gives perfect positioning of an object. The distance from a known point to two other points and the distance between those two points puts all three positions accurately. I suppose GPS satellite navigation has superseded it.

The direction the signal is coming from is detected from 2 points, and a straight line can be drawn towards that point, but not hit it, with the 2 points the signal is coming from where the 2 lines intercept.

A brilliant piece of hyperbole, taking the ordinary and giving it drama. Love this poem ma, You know I have a thing for coffee!

To put it very very easy:
They spot the BTS (repeater) the cellphone is connected to
