Which sequence of transformations creates a similar, but not congruent, traingle.
a) rotation and translation
b) reflection and rotation
c) dilation and rotation
d) translation and reflection

Option C. dilation and rotation

Step-by-step explanation:

we know that

Rotation, translation and reflection are transformations that create congruent triangles, since the dimensions of the triangles do not change.

An dilation is a transformation that creates similar triangles, because the dimensions of the triangles change

therefore

In this problem

The sequence of transformations that creates a similar, but not congruent, triangle is the option C

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
