The algebraic rule for a figure that is rotated 270° clockwise about the origin is (y, -x). Therefore, the algebraic rule for a figure that is rotated 270° clockwise about the origin is (y, -x) Notice how the octagons sides change direction, but the general. In the figure below, one copy of the octagon is rotated 22 ° around the point. Notice that the distance of each rotated point from the center remains the same. Therefore, the coordinate of a point (3, -6) after rotating 90° anticlockwise and 270° clockwise is (-6, -3). In geometry, rotations make things turn in a cycle around a definite center point. Rotating 270° clockwise, (x, y) becomes (y, -x) Rotating 90° anticlockwise, (x, y) becomes (-y, x) Given, the coordinate of a point is (3, -6) What will be the coordinate of a point having coordinates (3,-6) after rotations as 90° anti-clockwise and 270° clockwise? A corollary is a follow-up to an existing proven theorem. A short theorem referring to a 'lesser' rule is called a lemma. These are usually the 'big' rules of geometry. We will add points and to our diagram, which. First a few words that refer to types of geometric 'rules': A theorem is a statement (rule) that has been proven true using facts, operations and other rules that are known to be true. Now, consider the point ( 3, 4) when rotated by other multiples of 90 degrees, such as 180, 270, and 360 degrees. Here you can drag the pin and try different shapes: images/rotate-drag. In general terms, rotating a point with coordinates (, ) by 90 degrees about the origin will result in a point with coordinates (, ). Every point makes a circle around the center: Here a triangle is rotated around the point marked with a '+' Try It Yourself. Rotating a figure 270 degrees clockwise is the same as rotating a figure 90 degrees counterclockwise. 'Rotation' means turning around a center: The distance from the center to any point on the shape stays the same. The amount of rotation is called the angle of rotation and it is measured in degrees. So the rule that we have to apply here is (x, y) -> (y, -x). Step 2 : Here triangle is rotated about 90° clock wise. The fixed point is called the center of rotation. Step 1 : First we have to know the correct rule that we have to apply in this problem. What is the algebraic rule for a figure that is rotated 270° clockwise about the origin?Ī rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.
