Question

The point (3, 5) after 180° clock wise rotation is

  1. (- 3,   - 5)
  2. (- 3,  5)
  3. (3,   - 5)
  4. (5,  3)

hintHint:

A rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.

The correct answer is: (- 3,   - 5)


    The point (3,5) after rotation of 180° about the y axis is (-3,5).
    Hence, the correct option is A.

    Points can be rotated about any of the two axes or the origin or about a line.

    From the given transformation which pre image is not equal to image

    Transformation is a mechanism that transform an object into different structures.
    In General, there are 4 types of transformations. They are;
    1. Reflection
    2. Rotation
    3 Translation
    4. Dilation.
    Except Dilation, all the transformation techniques are termed as rigid transformations since, they provide same structure as the object.

    * Transformation is the mechanism that changes one image to other by performing the below techniques.
    * Reflection, Rotation, Dilation, Translation.
    * Since, In Reflection, Rotation, Dilation the size and shape of the object remains constant. They were called as Rigid Transformation.
    * In Dilation, the object's structure got changed and hence, it is termed as a non- rigid Transformation.

    Given Data:
                      In the transformation rotation at what degree measure image match with its pre image.
    >>>We were asked to find the Angle of Rotation that rotates to exactly to it's point.
    >>>Hence, let the point in the space be (x, y) then it's rotation should be (x, y).
    >>>Finely, The rotated coordinates are in the form:
    (x', y') =  left parenthesis x space cos alpha space minus space y space sin alpha space comma space y space cos alpha space plus space x space sin alpha right parenthesis
    >>>From the given data:
    (x', y') = (x, y)
    * By comparing the above Equation's we get:
    x = (x cosalpha - y sinalpha) and y = y cosalpha + x sinalpha
    >>>By solving the above Equation's we get:
              (x cross times y) =  (x cross times y) cosalpha - y2 sinalpha
