Overall, researchers concluded that the 135-degree reclining position put the least stress on the spine and may reduce the risk of back pain. The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse. A new study suggests that sitting upright for hours at a time -- for example, when working at a computer -- may lead to chronic back pain. The Full Circle. The angle is the same as an angle in polar coordinates of the component of the vector in the xy-plane and is normally measured in radians rather than degrees. 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 . Using "positional" magnetic resonance imaging (MRI) researchers studied the sitting positions of 22 healthy volunteers with no history of back pain. It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle.

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. This bizarre house really doesn't have an official name, but it does have a 135 degree angle. "This may be all that is necessary to prevent back pain, rather than trying to cure pain that has occurred over the long term due to bad postures," says Bashir. For example, two 45-degree angles add up to a 90-degree corner. An acute angle falls somewhere between nonexistent and a right angle (see Figure 4). Two 30-degree miters equal a 60-degree corner. And you can see from our measure right over here that that gives us a 90 degree angle. It's a very interesting angle. It is equal to one-quarter of a rotation around a circle. It is called a "right angle." Galleries Protractors. A protractor indicating a measurement of 135 degrees from the right side. 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.
