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.

What is the Angle Bisector theorem? Answer: As you can see in the picture below, the angle bisector theorem states that the angle bisector, like segment AD in the picture below, divides the sides of the a triangle proportionally. Example. The picture below shows the proportion in action. Answer.
