We can have one exercise for all transformations or an exercise for each transformation (in the latter case, we can ask about a single property each time (and of course we should interleave those exercises))

Triangle

△ A B C

is translated

2

units down and

6

units to the right.

Which of the properties remain the same after the transformation?

	Same	Not the same
The measure of $∠ A$ ‍
The coordinates of $B$ ‍
The area of the triangle

Possible properties:

Coordinates of points
Lengths of sides
Measures of angles
Area
Perimeter
Slopes of sides (or lines being parallel)

Possible transformations:

Translations
Rotations
Reflections
Dilations
Stretches?
Other?
