It is used to identify AA meeting places and used on AA coins to recognize sobriety time. Together they represent perfect union of mind and body.Īlthough, in the early 1990’s AA began to phase out the use of the circle and triangle on all conference approved literature it is still widely regarded as the “unofficial” logo of the fellowship. The circle symbolizes serenity and perfection, and the source of unlimited potential. The body should be triangular, stable, and the mind circular and open. In AA, the equilateral triangle represents the three part answer – Unity, Recovery, and Service – to a three part disease – Physical, Mental, and Spiritual, while the circle represents AA as a whole. Louis in 1955, and from that point on was widely used in the Fellowship. For an obtuse triangle, the circumcenter is outside the triangle. Some outer edges of the picture may be cropped away. Solution for The sides of triangle are 8cm, 10cm and 14cm. It was adopted as an official symbol at the International Convention in St. Crop an image to a shape, such as a circle Fill Fills the entire shape with the picture. This can be determined by finding the point of concurrency of the angle bisectors of each. Every triangle has three distinct excircles, each tangent to one of the triangle's sides. The largest circle that can be inscribed in a triangle is incircle. 1 An excircle or escribed circle2 of the triangle is a circle lying outside the triangle, tangent to one of its sides and tangent to the extensions of the other two. The Circle and Triangle symbol has long been connected with the AA Fellowship. The center of the incircle is a triangle center called the triangle's incenter. The five points of the pentagram represent five basic elements: earth, air, fire, water and spirit. Far from being an evil symbol the pentagram represents protection, the self, or the spirit. The priests and seers of antiquity regarded the circle enclosing the triangle as a means of warding off the spirits of evil, and AA’s circle and triangle of Recovery, Unity, and Service has certainly meant all of that to us and much more.”īill W., Alcoholics Anonymous Comes of Age (p.139) A pentagram (or pentacle) is a circled five-pointed star that most people associate with witchcraft or satanism. Finally, if the triangle is right, the orthocenter will be the vertex at the right angle. That we have chose this particular symbol is perhaps no accident. If the triangle is obtuse, the orthocenter will lie outside of it. Within our wonderful new world, we have found freedom from our fatal obsession. Every triangle has three distinct excircles, each tangent to one of the triangle's sides. Taking this result into my second diagram you can see that the line from each vertex of triangle ABC to the centre of the incircle produced bisects the vertex angle and the opposite side.įurther these lines meet the opposite sides at right angles, since OF, OG, OH are radii and the sides are tangents.įurther these lines meet at the centre of the incircle.The circle stands for the whole world of AA, and the triangle stands for AA’s Three Legacies of Recovery, Unity and Service. An excircle or escribed circle of the triangle is a circle lying outside the triangle, tangent to one of its sides and tangent to the extensions of the other two. Therefore OP bisects any line such as MN, crossing PM and PN produced Since OM and ON are radii and NP and MP are tangents \hat and the two tangents To see why the tangent point is the mid point of each side look at my first sketch for some preliminary results.įrom any point P outside any circle, centre O, two tangents may be drawn meeting the circle at M and N. The inscribed circle for any polygon is the circle to which each side is tangent. I have no idea what the 'two circles theorem' is but you seem to be discussing the incircle for a triangle.
