Transformations and Reflections Vocabulary

This transformation takes the geometric figure and "flips" it over a line.

• rotation

• translation

• dilation

• reflection

Answer explanation

"Flipping" a figure over the line results in a reflected version of the figure. This is why we call it a reflection.

The mathematical term for the line that you reflect a shape over is the...

• Mirror

• Reflective tape

• Line that you reflect over

• Line of reflection

Answer explanation

The line that a figure is reflected over is called the line of reflection.

What is the sequence of transformations for the image given?

• Reflect over the x-axis, translate (x+8,y)

• Reflect over the x-axis then translate (x+6, y)

• Reflect over the y-axis then (x+1, y+1)

• Translate down 4 (y-4) and to the right 5 (x+5)

Answer explanation

The orientation of the labels indicate that the figure was reflected, not rotated, as they are mirrored from the original preimage.

Then, a translation would result in the figure being positioned where it is shown.

Rank yourself on how confident you currently feel about what's been covered so far in Unit 5 (Transformations vocabulary, Translations, Rotations, and Reflections)

• I'm totally lost and guessing on everything.

• I'm pretty confused about most of it.

• I feel good about it when we talk about it in class and with the videos, but I'm still having trouble completing problems on my own.

• I feel pretty good about it for the most part.

• I feel great about everything we've covered and could even show someone else how to do it.

Answer explanation

If you answered 1-3, be sure to take advantage of office hours!
