To help you visualize the Sails, you can also use string stretched between your planned attachment points. The first step is to measure. Then make a scale drawing of the area you want shaded. 1/4 (or 1/8) inch = 1 foot. Then cut out scale drawings of the ready-made shade sails. Rotate them around to get ideas for the lay-out. Imagine a straight line from the center of the shade sail through the corner ring, that is where you need to put the attachment point.
Angle Bisectors in a Triangle. The definition of the angle bisector of a triangle is a line segment that bisects one of the vertex angles of a triangle. In general, an angle bisector is equidistant from the sides of the angle when measured along a segment perpendicular to the sides of the angle.

In these situations, the bisecting angle technique may be used. The film can be held in the mouth with the bite block or a bisecting instrument may be used. Note: patient acceptance of the bisecting instrument is not much better than for the paralleling instrument.Size #2 Film is used for Anterior and Posterior X-rays when Bisecting. The snap-a-ray is used.isadvantages When comparing the two periapical techniques, the disadvantages of the bisecting angle technique are: The Bisecting Angle Technique is an alternative to the paralleling technique for taking periapical films.
