Do you know what isometric means?

eboogie4 · Answer

@Maddiem no i dont

anthonyym · Answer

An isometric transformation preserves the dimensions of the figure. Unless the length or width changes then it's in isometry.

anthonyym · Answer

For example a dilation (streching or shrinking) of a figure is not an isometry because a dilation changes the dimensions of the figure.

oh C

anthonyym · Answer

You're saying it's C? https://media.education2020.com/evresources/2089799_5fee9d1f-225b-4223-995b-3965a143a9b8.png

C or D

anthonyym · Answer

Why do you think it's C and why do you think it's D?

eboogie4 · Answer

Either D cause its size changed or C cause it just turned it

anthonyym · Answer

Rotations are still isometric transformations because the dimensions of the figure don't change. Its length is still 4 blocks wide and its width is still 1 block wide.

bobo-i-bo · Answer

An isometry is any transformation which preserves size, i.e. as long as dilation/enlargement is not involved, then the the transformation is isometric
