Cedric applied the rule to figure WXYZ.

Figure W X Y Z is reflected across the line of reflection m to form W prime X prime Y prime Z prime. Figure W prime X prime Y prime Z prime is rotated 180 degrees about point P to form W double-prime X double-prime Y double-prime Z double-prime.
What mistakes did he make? Select two options.

He applied the reflection to the pre-image first.
He applied the rotation to the pre-image first.
He changed the size of the figure instead of just applying a rotation.
He used point P as the center of rotation.
He used an incorrect angle of rotation around point P.

Transformation involves changing the position and/or size of a shape.

Cedric's mistakes are:

  • He applied the reflection to the pre-image first.
  • He used an incorrect angle of rotation around point P.

The transformation rule used by Cedric is

[tex]R_p,90^o(x,y) \cdot\ r_m[/tex]

While the actual transformation is:

[tex]r_m\cdot R_p\ 180^o(x,y)[/tex]

First, we analyze the actual transformation, [tex]r_m\cdot R_p\ 180^o(x,y)[/tex]

The above transformation means that

  • WXYZ is first reflected across line m
  • Then, it was rotated 180 degrees about point P

However, [tex]R_p,90^o(x,y) \cdot\ r_m[/tex] means that:

  • WXYZ was rotated by 90 degrees about point P
  • Then, it was first reflected across line m

By comparing the above statements to the list of given options, the mistakes he made are:

  • He reflected WXYZ, first
  • Incorrect angle of rotation at point P
