Can 3 towers placed equidistant at the same latitude demonstrate curvature?

If 3 towers are placed equidistant at the same latitude will the middle tower appear offset when lining up in view either end Tower? I call it looking over Earth’s shoulder.

Yes, consider, for example, three very tall towers at various points on the arctic circle

Here's three 800km high towers on the 45°N line of latitude:

It's not something that's actually practical. But perhaps useful for getting an understanding of how lines of latitude differ from great circles. Here's the great circle (shortest distance over the globe) between the two outside towers. 20171110-102307-ro65s.jpg
