What are the internal angles of a square based pyramid?

Answer 1

A square-based pyramid has a total of eight internal angles: four at the base, which are right angles (90 degrees each), and four at the apex where the triangular faces meet. The angles at the apex depend on the specific dimensions of the pyramid but typically are less than 180 degrees and vary based on the height and slant of the sides. Each triangular face contributes two angles at the base and one angle at the apex, totaling 720 degrees for the whole pyramid. However, the most common angles of interest are those at the base.
