![]() ![]() The angle goes from the center to first point, then from the center to the image of the point. A 90 degree turn is 1/4 of the way around a full circle. ![]() To fully describe a rotation, it is necessary to specify the angle of rotation, the direction, and the point it has been rotated about. We can think of a 60 degree turn as 1/3 of a 180 degree turn. To understand rotations, a good understanding of angles and rotational symmetry can be helpful. Step 2: After you have your new ordered pairs, plot each point. Step 1: For a 90 degree rotation around the origin, switch the x, y values of each ordered pair for the location of the new point. and a multiple of 90° (90°, 180° or 270°) is used. Rotating a polygon clockwise 90 degrees around the origin. If necessary, plot and connect the given points on the coordinate plane. or anti-clockwise close anti-clockwise Travelling in the opposite direction to the hands on a clock. Step 1: Note the given information (i.e., angle of rotation, direction, and the rule). You see that that is equivalent, that is equivalent to a 90 degrees, to a 90 degrees clockwise rotation, or a negative 90 degree rotation. Rotations can be clockwise close clockwise Travelling in the same direction as the hands on a clock. Were going in a counter-clockwise direction. This point can be inside the shape, a vertex close vertex The point at which two or more lines intersect (cross or overlap). Rotation turns a shape around a fixed point called the centre of rotation close centre of rotation A fixed point about which a shape is rotated. The result is a congruent close congruent Shapes that are the same shape and size, they are identical. Rotations may be clockwise or counterclockwise. An object and its rotation are the same shape and size, but the figures may be turned in different directions. is one of the four types of transformation close transformation A change in position or size, transformations include translations, reflections, rotations and enlargements.Ī rotation has a turning effect on a shape. A rotation is a transformation that turns a figure about a fixed point called the center of rotation. A rotation close rotation A turning effect applied to a point or shape.
