Do you know anything about similar figures?

OpenStudy (rainbow_rocks03):

ops I didnt mean to put down that question I only meant to put the second one

OpenStudy (anonymous):

That is good though. If you know the answer to the first question, you should be able to solve the second equation.

OpenStudy (rainbow_rocks03):

really? let me look at it again

OpenStudy (rainbow_rocks03):

hang on real quick. :)

OpenStudy (anonymous):

That's all right, take your time. :)

OpenStudy (rainbow_rocks03):

thank you

OpenStudy (rainbow_rocks03):

I am trying to figure out the second question but I am stuck. :/

OpenStudy (anonymous):

Okay, what was your answer for the first question?

OpenStudy (rainbow_rocks03):

My answer for the first question was the last one - Both (a) and (b)

OpenStudy (anonymous):

Good, B states that the sides should form equivalent ratios. Take choice B for example: Side A: 10/20=2, Side B: 7/14=2, Side C: 15/28= 0.535 Since 0.535 is not equal to 2, B is incorrect.

OpenStudy (anonymous):

In my first statement, B refers to the second choice for the first question, while from then on it meant the second choice in the second question. Sorry if there wads any confusion.

OpenStudy (anonymous):

*was

OpenStudy (rainbow_rocks03):

I am confused. 😬

OpenStudy (anonymous):

Alright, if you take a side of the figure represented and divided it by a side for one of the triangles in the answer choices you should get a number. When all three of these numbers match, you have your answer.

OpenStudy (rainbow_rocks03):

?

OpenStudy (anonymous):

Okay, take option A. The side lengths are 30, 21, and 45 Side A: 30/10=3, Side B: 21/7=3, Side C: 45/15=3 Because all the numbers match, it is your answer. Get it?

OpenStudy (anonymous):

This means that the triangle that choice A represents is a similar triangle just scaled by a factor of 3

OpenStudy (rainbow_rocks03):

ohhhh, I think I get it now

OpenStudy (anonymous):

Cool, if that's all then.

OpenStudy (rainbow_rocks03):

so my answer is the first one right?
