Right angle Right angle In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles. The term is a calque of Latin "angulus rectus"; here "rectus" means "upright", referring to the vertical perpendicular to a horizontal base line. Closely related and important geometrical concepts are perpendicular lines, meaning lines that form right angles at their point of intersection, and orthogonality, which is the property of forming right angles, usually applied
Right-angle weave Right-angle weave Right-Angle weave stitch, also known as RAW, is an off-loom bead weaving technique. Beads are stitched together with thread only making right angle turns, hence the name. The result is an almost fabric like piece of beadwork. Right-Angle weave can be woven with either one needle or two. With single needle right-angle weave, the thread path moves in a figure-eight pattern. For double needle right-angle weave, the threads cross each other along the center bead of each stitch as they head in opposite directions. RAW can be formed into flat pieces, tubes, or 3 dimensional figures. There are
