ANSWER
Dilation
EXPLANATION
The given regular polygon is an equilateral triangle.
If we dilate this polygon about the origin with a scale factor of 1.
The image triangle will coincide with the preimage.
Therefore the transformation that will carry the given regular polygon on to itself is dilation.
The correct choice is C.

Congruent triangles are all the same. Given that the faces of a triangular pyramid are congruent then all its faces are the same. It is also good to note that this pyramid has 4 faces. Given that the surface area of the pyramid is 372m^2, the area of one face will be:
area=(total area)/(number of faces)
=372/4
=93 m^2
Suppose the sides of the big triangle are called m, x and 12+4=16. We have that the big triangle and the small triangle to the right of the shape (sides x,y,12) are similar. We can take then the ratios of correponding sides and know that they will be equal. Thus, we have that 4/y=y/12. Hence, y*y=48. Thus y=
