Reflections

The image of a reflection is congruent to the preimage.

Which line above is considered the 'mirror' in this reflection?

A reflection over a mirror is the same as a 180 degree rotation about a point on the mirror.

Choose all statements below that are true.

Consider a line on your desk and a point P. Explain how you would find P' , the image of P reflected over the line on your desk. Be specific about what you would have to measure in order to locate P'.

Use a graph board or Geogebra in another window to visualize and find the indicated point.

Enter the coordinates of P' which is the reflection of P(3,5) over the y-axis.

Enter your answer with no spaces in the form (a,b).

Use a graph board or Geogebra in another window to visualize and find the indicated point.

Enter the coordinates of P' which is the reflection of P(3,5) over the x-axis.

Enter your answer with no spaces in the form (a,b).

Use a graph board or Geogebra in another window to visualize and find the indicated point.

Enter the coordinates of P' which is the reflection of P(3,5) over the line y = x.

Enter your answer with no spaces in the form (a,b).

Write about what you have learned about reflections. Be sure to incorporate specific mathematical measurements that are the key to ensuring a proper reflection.
