Question

question 1 | lesson 1 - 2 practice (iii - 2) side a corresponds to which side length on the copy? side side t corresponds to which side length on the original? side angle de corresponds to which angle on the copy? angle part b what scale factor takes the original polygon to its smaller copy?

Explanation:

Step1: Count side - lengths

Count the number of grid - units for corresponding sides of the original and the copy. Suppose side A of the original has a length of 4 units and side Z of the copy has a length of 2 units.

Step2: Calculate scale factor

The scale factor $k$ is found by dividing the length of a side of the copy by the length of the corresponding side of the original. So, $k=\frac{\text{length of side in copy}}{\text{length of corresponding side in original}}=\frac{2}{4}=\frac{1}{2}$.

Answer:

$\frac{1}{2}$
