Which of the following best describes the property of Lambert charts regarding angular measurements?

Lambert charts are specifically designed to maintain true angles between lines, which is a crucial property for navigation and graphical representation. This preservation of angular relationships makes them particularly useful for pilots and navigators, as it allows for accurate course plotting. When using a Lambert chart, the angles at which two paths intersect will reflect the actual angles those paths make in real-world navigation, which is essential when planning routes that require precise bearing calculations.

While it is true that Lambert charts can introduce some distortion in other measurements, particularly in the representation of distances and areas, their primary utility lies in angle preservation. This capability is critical for navigating accurately, as it allows users to plot and follow courses based on consistently maintained angles, thereby ensuring that flight paths remain true to intended trajectories. The focus on angle maintenance is why Lambert charts are preferred in certain aeronautical applications.
