The sides and angles of a rectangle: Opposite sides of a rectangle are the same length (congruent). As well as measuring the angle differently, in mathematical applications theta , θ , is very often used to represent the azimuth rather than the representation of symbol phi φ . Introduction - An For example, two 45-degree angles add up to a 90-degree corner. Researchers used the MRI to examine spinal positioning while the participants assumed three different sitting positions: slouching forward (such as hunched over a desk or video game console), an upright 90-degree sitting position, and a relaxed position with the back reclined backward about 135 degrees while the feet were still on the floor. The shortest side is across from the smallest angle, the middle-length side is across from the mid-sized angle, and — surprise, surprise — the longest side is across from the largest angle.The ratio of sides doesn’t equal the ratio of angles. The rays span out to accommodate the width of the house, with the apex located at the centerline of the house and the open end of the angle facing downward. "A 135-degree body-thigh sitting posture was demonstrated to be the best biomechanical sitting position, as opposed to a 90-degree posture, which most people consider normal," says researcher Waseem Amir Bashir, MBChB, clinical fellow in the department of radiology and diagnostic imaging at the University of Alberta Hospital, Canada, in a news release.
