Question

26 find the scale factor of trapezoid qrst if it is dilated to qrst. type your result in the empty box provided below. answer:

Explanation:

Step1: Determine the length of a side in QRST

Let's take the length of QR. From the graph, Q is at (-5, 3) and R is at (-1, 3) (assuming grid units). The length is $|-1 - (-5)| = 4$.

Step2: Determine the length of the corresponding side in Q'R'S'T'

Q' is at (-9, 7) and R' is at (-1, 7). The length is $|-1 - (-9)| = 8$.

Step3: Calculate the scale factor

The scale factor is the ratio of the length of the dilated figure to the original figure. So, scale factor = $\frac{8}{4} = 2$.
