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.

(Redirected from Angle bisector) Line DE bisects line AB at D, line EF is a perpendicular bisector of segment AD at C, and line EF is the interior bisector of right angle AED. In geometry, bisection is the division of something into two equal or congruent parts, usually by a line, which is then called a bisector. The most often considered types of bisectors are the segment bisector and the angle bisector. In three-dimensional space, bisection is usually done by a plane, also called the bisector or bisecting plane.
