Which transformations will produce similar, but not congruent, figures?

triangle tuv is rotated 270° clockwise and then translated 12 units down to form triangle t"u"v" .

triangle tuv is rotated 180° counterclockwise and then reflected across the x-axis to form triangle t"u"v" .

triangle tuv is translated 3 units left and 4 units up and then reflected across the y-axis to form triangle t"u"v" .

triangle tuv is dilated by a scale factor of 9 and then translated 2 units right and 1 unit down to form triangle t"u"v" .

In first three options you are talking about , rotation , Translation and Reflection . When you take these qualities into consideration about a triangle neither the shape , nor size of image changes after Rotation, Translation, and Reflection.

So , First three options are incorrect.

And Fourth option→→→ Triangle TUV is dilated by a scale factor of 9 and then translated 2 units right and 1 unit down to form triangle T"U"V"  produces similar figures, which are not congruent.

→T U V ~ T" U" V"→→→→ When Dilation is done two figures are similar. Because in Dilation Either Preimage stretches or Shrank .The Resulting Image is Similar to Preimage.

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?
