Geometry rotation rules clockwise how to#

To fully describe a rotation, it is necessary to specify the angle of rotation, the direction, and the point it has been rotated about. To understand rotations, a good understanding of angles and rotational symmetry can be helpful. A rotation can move in two directions, clockwise or counterclockwise.

The figure can rotate around any given point. ROTATIONS A rotation is a transformation that TURNS a figure around the origin (0, 0). Rotation Rules Rotations Rules On this lesson, you will learn how to perform geometry rotations of 90 degrees, 180 degrees, 270 degrees, and 360 degrees clockwise and counter.

If the number of degrees are negative, the figure will rotate clockwise. If the number of degrees are positive, the figure will rotate counter-clockwise.

and a multiple of 90° (90°, 180° or 270°) is used. Although a figure can be rotated any number of degrees, the rotation will usually be a common angle such as 45 or 180. The general rule for a rotation by 180 about the origin is (A,B) (-A, -B) Rotation by 270 about the origin: R (origin, 270) A rotation by 270 about the origin can be seen in the picture below in which A is rotated to its image A'. or anti-clockwise close anti-clockwise Travelling in the opposite direction to the hands on a clock. Rotations can be clockwise close clockwise Travelling in the same direction as the hands on a clock. Let us learn the rotation formula along with a few. In general, rotation can be done in two common directions, clockwise and anti-clockwise or counter-clockwise direction. Rotation is a circular motion around the particular axis of rotation or point of rotation. This point can be inside the shape, a vertex close vertex The point at which two or more lines intersect (cross or overlap). The rotation formula is used to find the position of the point after rotation. 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. 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. Rotation can have a sign (as in the sign of an angle): a clockwise rotation is a negative magnitude so a counterclockwise turn has a positive magnitude. What is the rule for a 90 counter clockwise rotation about the origin (x,y).

A rotation close rotation A turning effect applied to a point or shape.
