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.

An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.By the Angle Bisector Theorem, Proof: Extend to meet at point E. By the Side-Splitter Theorem, ---------(1). The angles are corresponding angles.So, Since is a angle bisector of the angle. By the Alternate Interior Angle Theorem, Therefore, by transitive property, Since the angles are congruent, the triangle is an isosceles triangle with AE = AB. Replacing AE by AB in equation (1), Example : Find the value of x.he angles are corresponding angles. So, Since is a angle bisector of the angle.
