Which of he following statements is true of a reflection? select all that apply.
it is an isometry.
it slides a plane.
the transformation is done over a line of reflection.
it flips a plane about a fixed line.
it changes the size of the figure being reflected.

 It is an isometry.

The transformation is done over a line of reflection.

It flips a plane about a fixed line.

Step-by-step explanation:

We know that on the coordinate plane , a reflection is a type of rigid transformation flips a shape across a given line without changing its shape and size of the figure.

It is said to be isometry because the original figure and its image after reflection are congruent .

Thus it does not change the size of the figure .

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

the answer is ! ?
