Remote interior angles are the angles that are not adjacent to a given exterior angle but are inside the triangle. For each exterior angle of a triangle, there are two remote interior angles. The sum of these remote interior angles is equal to the measure of the exterior angle. Thus, if you have a specific exterior angle, you can identify the two corresponding remote interior angles.

The interior of the Australian continent is commonly referred to as the "Outback." This vast and remote region is known for its arid landscapes, unique wildlife, and sparse population.

The middle part of Australia has no particular name. The very centre is commonly called the Red Centre, due to the landscape characterised by red sand and bulldust. Much of the vast interior is called the Outback, a general term that refers to any region remote from major settled areas.
Lakes in Australia are still called lakes. However, many of those in the interior are salt lakes, and because they tend to be dry much of the time, they are called saltpans.
For a polygon with n sides (n angles), there are (n - 1) remote interior angles for each exterior angle.
