6. describe some things you could notice in two polygons that would you decide

that they were not scaled copies.

Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase.

Step-by-step explanation:

In this question, we need to tell some things that could help to check if two polygons are scaled copy of each other or not.

Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase. For example, if a rectangle has a length of 10 and a height of 8, a scaled copy would be a length of 5 and a breadth of 4.

Another example is as follows:

If a rectangle has a length of 4 and a height of 3, a scaled copy would be a length of 8 and a breadth of 6.

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
