Transformation

Transformation of geometric figures can be defined as the creation of duplicate object retaining the shape and certain properties of the original object. Transformation can be classified as following

  • Translation
  • Rotation
  • Reflection
  • Resizing (or Scaling)

Translation

Translation is a type of transformation where the duplicate object is created by moving every point of the original object by a certain distance. The following figure shows the translation of a triangle.

Translation

Rotation

Rotation is a type of transformation where the duplicate object is created by rotating every point of the original object by a certain angle about a point called Centre of rotation. The figure below shows the rotation of a triangle.

Rotation

Reflection

Reflection is a type of transformation where the duplicate object is the mirror image of the original object. Here the object gets reflected about a line which is called as line of reflection. The figure below shows the reflection of a square about the reflection line.

Reflection

Resizing (or Scaling)

Resizing or Scaling is a type of transformation where the original object is proportionally decreased or increased to get the duplicate object. The size of the duplicate object will be increased or decreased by certain amount. This change in size is called scaling and the factor by which the size is increased/decreased is called scaling factor. The figure below shows the resizing of a triangle.
