What is the capable bow

In this new video I'm going to explain what the capable bow.

The capable bow it is the locus of the points from which a segment AB is seen with the same angle. That is, with the locus of the vertices of the angles that have the same breadth, cover the same segment.

The arc capable of a segment AB of angle alpha, is a pair of symmetrical circumference arcs of both the lower and upper part of the segment. On each side of the segment AB that contains the vertices of the angle alpha. Any point on the arc will always contain the same alpha angle. The center of the semicircle, if we draw a triangle, will be a double vertex (2 alpha). In the video we will see this exercise graphically.

Know the properties of capable bow It is very useful in technical drawing to solve geometric problems related to angles of triangles.

exist three systems or methods To find the capable bow that you can learn to do by watching the video.

Also, if you want to practice what you learned in today's class, you can do the printable exercises with their solutions that I have left you on the web.
