Question

lesson 3 practice problems

1. here are 3 polygons.

a
draw a scaled copy of polygon a using a scale factor of 2.
b
draw a scaled copy of polygon b using a scale factor of $\frac{1}{2}$.
c
draw a scaled copy of polygon c using a scale factor of $\frac{3}{2}$.

Explanation:

Step1: For Polygon A with scale - factor 2

Multiply the length of each side of Polygon A by 2. Then, using a ruler and a protractor (if needed to maintain the angles), draw the new polygon with the new side - lengths.

Step2: For Polygon B with scale - factor $\frac{1}{2}$

Measure the length of each side of Polygon B. Divide each side - length by 2. Then draw the new polygon with these reduced side - lengths, keeping the angles the same.

Step3: For Polygon C with scale - factor $\frac{3}{2}$

Measure the length of each side of Polygon C. Multiply each side - length by $\frac{3}{2}$. Then draw the new polygon with these new side - lengths, maintaining the angles.

Answer:

You need to perform the above - described drawing operations on paper with appropriate tools (ruler, protractor) to get the scaled copies of Polygons A, B, and C.
