Answer:
1. In topography, the angle made by two ground lines is measured horizontally, and is called a horizontal angle. You may replace these ground lines by two lines of sight AB and AC. These lines of sight are directed from your eyes, which form the summit A of the angle BAC, towards permanent landmarks such as a rock, a tree, a termite mound, a telephone pole or the corner of a building.
Horizontal angles are usually expressed in degrees. A full circle is divided into 360 degrees, abbreviated as 360
Each degree is divided into smaller units:
A rectangular or a square shape has four straight sides and four interior 90 angles. The sum of these four interior angles is equal to 360
The sum of the four interior angles of any four-sided shape is also equal to 360, even if they are not right angles.
