_Diminished_ ANGLE, only used by some engineers, especially the Dutch, is composed of the face of the bastion, and the exterior side of the polygon. ANGLE _of the shoulder_, or ANGLE _of the épaule_, Is formed by one face, and one flank of the bastion. See FORTIFICATION. ANGLE _of the tenaille_, ANGLE _rentrant_, Is made by two lines fichant, that is, the faces of the two bastions extended till they meet in an angle towards the curtain, and is that which always carries its point towards the out-works. See FORTIFICATION. ANGLE _of the flank exterior_, is that which is before the centre of the curtain, formed by the prolongation of the faces of the bastion, or by both the fichant lines of defence, intersecting each other on planning a fortification. ANGLE _of the flank interior_, is formed by the flanked line of defence and the curtain; being that point where the line of defence falls upon the curtain. ANGLE _of the line of defence_, is that angle made by the flank, and the line of defence. ANGLE _of the face_, is formed by the angle of the face and the line of defence produced till they intersect each other. ANGLE _of the base interior_, is the half of the figure, which the interior polygon makes with the radius, when they join each other in the centre; intersecting the centre of the gorges of each bastion. ANGLE _of the base exterior_, is an angle formed by lines drawn from the centre of the figure, to the angle of the exterior polygon, cutting the centre of the gorges of each bastion. ANGLE _of the gorge_, is that angle formed by the prolongation of the curtains, intersecting each other, in the centre of the gorge, through which the capital line passes. ANGLE _of the ditch_, is formed before the centre of the curtain, by the outward line of the ditch. ANGLE _of the mole_, is that which is made before the curtain where it is intersected. _Flanked_ ANGLE. See ANGLE _of the bastion_. _Saliant_ ANGLE, ANGLE _sortant_, Is that angle which points outwards, or towards the country. Such is the angle of the counterscarp before the point of a bastion. _Entering_ ANGLE, or ANGLE _rentrant_, An angle pointing inwards, as the saliant angle does outwards. Such is the angle of the counterscarp before the curtain. ANGLE _of the counterscarp_, made by two sides of the counterscarp, meeting before the centre of the curtain. ANGLE _at the circumference of a circle_, is an angle formed by two chords in the circumference of a circle. ANGLE _of the circumference_, is the mixed angle formed by an arch, drawn from one gorge to another. _Re-entering_ ANGLE. See _Entering_ ANGLE. ANGLE _of the complement of the line of defence_, is the angle formed by the intersection of the two complements with each other. ANGLES _of a battalion_, are made by the last men at the extremity of the ranks and files. _Front_ ANGLES, the two last men of the front rank. _Rear_ ANGLES, the two last men of the rear rank.
