what is the scale factor in the following dilation? the red triangle is the original.

OpenStudy (anonymous):

OpenStudy (anonymous):

I want to hear your answer and reasoning first.

OpenStudy (anonymous):

so for the bottom of the triangle it gets bigger by an eztra 3, so it's 6 bottom bigger triangle. right?

OpenStudy (anonymous):

The question is, "what is the scale factor"? Whats your answer?

OpenStudy (anonymous):

so 3?

OpenStudy (anonymous):

is 3 the answer?

OpenStudy (anonymous):

Is 6 3 times as big as 3?

OpenStudy (anonymous):

because I noticed that all sides are equivalent

OpenStudy (anonymous):

OH wait it's 2!

OpenStudy (anonymous):

The red triangle...the base...is length 3. The original triangle...base is length 6. How many times larger is 6 than 3?

OpenStudy (anonymous):

Yes, 2.

OpenStudy (anonymous):

2 or wait is it a fraction?

OpenStudy (anonymous):

woohoo!

OpenStudy (anonymous):

Sorry, I didnt see your earlier response. Just divide, 6/3 = 2.

OpenStudy (anonymous):

thank you so much.

OpenStudy (anonymous):

Welcome.

OpenStudy (anonymous):

One last question I have for you.

OpenStudy (anonymous):

yes?

OpenStudy (anonymous):

make new Question.

OpenStudy (anonymous):

In the last diagram of the red and blue triangles, if the original triangle was the blue triangle and it is dilated to the red triangle, what would be the scale factor? (or as it is also called, the "constant of dilation").

I have a dog named Steve.

OpenStudy (anonymous):

hangonasec

OpenStudy (anonymous):

1/3?

OpenStudy (anonymous):

or 1/2?

OpenStudy (anonymous):

which one?

OpenStudy (anonymous):

1/3?

OpenStudy (anonymous):

How do you know 1/3?

OpenStudy (anonymous):

whats your reasoning?

OpenStudy (anonymous):

I think that if you dilate it bkwrds it is a reduction, right?

OpenStudy (anonymous):

You start with a length of 6. Now, you have a length of 3. So, yes, it is a reduction. What fraction does that represent?

OpenStudy (anonymous):

1/2

OpenStudy (anonymous):

Easier way to think about it............ what part of 6 is 3?

OpenStudy (anonymous):

Yes. Be careful with your arithmetic.

OpenStudy (anonymous):

half of it.

OpenStudy (anonymous):

Yes, the answer is a scale factor of 1/2.

OpenStudy (anonymous):

alrighty coolio.

OpenStudy (anonymous):

Good luck.

OpenStudy (anonymous):

do you go to connections academy?

OpenStudy (anonymous):

lol

OpenStudy (anonymous):

no?

OpenStudy (anonymous):

or are you old...

OpenStudy (anonymous):

No comment.
