Which composition of transformations will create a pair of similar, not congruent triangles? a) a rotation, then a reflectionb) a translation, then a rotationc) a reflection, then a translationd) a rotation, then a dilation

A rotation, then a dilation ⇒ answer D

Step-by-step explanation:

* Lets revise some facts on transformation

- A transformation is a change in the position, size, or shape of a

 geometric figure

- There are four main types of transformations: translation, rotation,

  reflection and dilation

- A rotation, translation, or reflection, does not change the size or

 shape of the figure

- Rotation , reflection and translation give congruent figures

- A dilation change the size of the figure by shrinks or enlarges it

- A composition of transformations is a combination of two or more

 transformations

- A similarity transformation is two rigid transformations reflection,

 followed by dilation or rotation, followed by dilation or translation

 followed by a dilation

∴ composition of transformations will create a pair of similar, not

  congruent triangles is a rotation, then a dilation

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

answer: you need to organize this better it does not make sense.
