Practice: Corresponding Parts and Scale Factors

If you are told that Shape 1 is similar to Sahpe 2, then select [b][u]all[/u] [/b][color=#ff0000]of the statements that [/color][b][color=#0000ff]MUST[/color][/b][color=#ff0000] be true[/color]:

Shape 1 has the same perimeter as Shape 2. Shape 1 has the same number of edges as Shape 2. The matching angles from Shape 1 and Shape 2 must be equal. The matching sides are all the same ratio from Shape 1 to Shape 2 Shape 1 is larger than Shape 2.

Polygon B, shown below, is a scaled copy of Polygon A. Answer the questions that follow.

What is the scale factor from Polygon A to Polygon B?

1 2.5 0.5 2
