Measurement of antinuclear antibodies (ANAs) in serum is the most commonly performed screening test for patients suspected of having a systemic rheumatic disease, also referred to as connective tissue disease.(1) ANAs occur in patients with a variety of autoimmune diseases, both systemic and organ-specific.
How do you rotate a figure 180 degrees in anticlockwise or clockwise direction on a graph? Rotation of a point through 180Â°, about the origin when a point M (h, k) is rotated about the origin O through 180Â° in anticlockwise or clockwise direction, it takes the new position M' (-h, -k).Worked-out examples on 180 degree rotation about the origin:n plotting the points P (-3, 1) and Q (2, 3) on the graph paper to get the line segment PQ. Now rotate PQ through 180Â° about the origin O in anticlockwise direction, the new position of points P and Q is: P (-3, 1) â P' (3, -1). Q (2, 3) â Q' (-2, -3). Thus, the new position of line segment PQ is P'Q'.
