Do you know what is special about a "Regular" pentagon?

anonymous · Answer

there is nothing special its  just has 5 sides that are congruent i think

anonymous · Answer

Right, all the sides are the same. So we have on pentagon with all sides being 4, and another with all sides being 8. Do you know the definition of a scale factor?

anonymous · Answer

yes it is a formula used for a problem.

anonymous · Answer

Haha, right, but not exactly what I meant. The scale factor is the ratio between the lengths of the sides of similar objects. Stated another way, it's what you have to multiply the length of the sides by to make the other object.

anonymous · Answer

yes ok

anonymous · Answer

In this case, we have sides of 4 and sides of 8. 8/4 = 2. Or, 4*2=8. Eitherway you want to look at it. Your scale factor (from the small to the large) is 2.

k thankx

anonymous · Answer

Oops, I misread the question. You are going from the large to the small. So the scale factor is one half ( or 0.5)

anonymous · Answer

ooo ok
thanx again
