Angaria, in civil law, implies a service by compulsion, as furnishing horses and carriages for conveying corn or other stores for the army.

ANGLE, in geometry, is the inclination of two lines meeting one another in a point.
Sometimes angles are denoted by a single letter placed at the point of intersection; but when several lines meet at the same point, each particular angle is denoted by three letters, whereof the middle letter shews the angular point, and the other two letters the lines which form that angle.
The measure of an angle is the arch of a circle, described on the angular point, intercepted between the two lines which form the angle, and as many degrees, &c. as are contained in that arch, so many degrees, &c. the angle is said to consist of.
Angles are either right, acute, or obtuse.
A Right Angle, is that whose two legs are perpendicular to each other; and consequently the arch intercepted between them is exactly 90° or the quarter of a circle.
