Question

Triangle A B C is reflected and then dilated to form smaller triangle A double-prime B double-prime C double-prime
Which transformations could have occurred to map △ABC to △A"B"C"?

a rotation and a dilation
a rotation and a reflection
a reflection and a dilation
a translation and a dilation

Answer 1

A reflection and a dilation.

Reflection produces the mirror image; the dilation (with scale factor <1) makes the triangle smaller, matching △A"B"C".
