Question

when a figure is dilated by a scale factor of 2, what happens to its size?
a. it triples in size
b. it becomes half its original size
c. it remains the same
d. it doubles in size

Explanation:

Step1: Understand dilation concept

Dilation is a transformation that changes the size of a figure. When the scale - factor is $k$, the new dimensions are $k$ times the original dimensions.

Step2: Analyze given scale factor

Here, the scale factor $k = 2$. So, each dimension of the figure is multiplied by 2. This means the figure doubles in size.

Answer:

d. It doubles in size
