The two figures are similar.

a) Write the similarity statement.
b) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
c) What is the scale factor? Explain.

Given:

Two similar figures.

Solution:

Part a:  

ΔABC and ΔA'B'C' are similar.

Similarity statement:

If two triangles are similar, then the corresponding sides are in proportion.

The sides are in the same ratio. Therefore the two triangles are similar.

Part b:

The sides of A'B'C' are greater than the original image ABC.

Therefore, the dilation A'B'C' is an enlargement.

Part c:

Scale factor:

K = 4

Scale factor = 4

K > 1

Therefore the image of the dilation is enlargement.

answer: procent 54 wynosi 33,33%
