Question

problem 1 is figure b a scaled copy of figure a? use the sketch tool if it helps to show your thinking. yes no

Explanation:

Step1: Check side - length ratios

Measure the side - lengths of corresponding parts of figure A and figure B. Let's assume the horizontal and vertical side - lengths of figure A are \(a_1,a_2\) and of figure B are \(b_1,b_2\). If figure B is a scaled copy of figure A, the ratio \(\frac{b_1}{a_1}=\frac{b_2}{a_2}\).
By counting the grid squares, for the vertical side of the main part of figure A, say \(a_1 = 2\) grid - squares and for figure B, \(b_1=4\) grid - squares. For the horizontal side of the main part of figure A, say \(a_2 = 2\) grid - squares and for figure B, \(b_2 = 6\) grid - squares. \(\frac{b_1}{a_1}=\frac{4}{2}=2\), \(\frac{b_2}{a_2}=\frac{6}{2}=3\). Since \(\frac{b_1}{a_1}
eq\frac{b_2}{a_2}\), the side - length ratios are not consistent.

Answer:

No
