Final answer:
To determine the type of dilation from triangle PRQ to P'R'Q', one must compare the side lengths or coordinates of the two triangles. A scale factor greater than 1 indicates an enlargement, while a scale factor less than 1 indicates a reduction.
Step-by-step explanation:
The question asks to describe the dilation performed on triangle PRQ to get triangle P'R'Q'. Without graphical information, we cannot visually inspect the dilation. However, according to the multiple-choice options provided, the triangle has either been enlarged or reduced by a certain scale factor. To determine whether it is an enlargement or reduction, you would normally compare the side lengths or coordinates of corresponding points between the two triangles. If the absolute value of the scale factor is greater than 1, it is an enlargement, whereas if it is a fraction less than 1, it's a reduction.
For example, if we had a triangle with sides of length 3 units, and through dilation, we got a triangle with sides of length 9 units, this would be an enlargement by a scale factor of 3, because 9 divided by 3 is equal to 3. Conversely, if the sides of the original triangle were reduced to 1 unit, this would be a reduction by a scale factor of 1/3, as 1 divided by 3 is 1/3.
