Question

Geometry and similarities! HELP!

Answer 1

@abbiewinter, Which choice do you believe is correct?

Answer 2

I honestly have no clue

Answer 3

\[\frac{BR}{DB} = \frac{\sqrt{1^2 + 2^2}}{\sqrt{2^2 + 4^2}} = \frac{\sqrt{5}}{\sqrt{20}} = \sqrt{\frac{5}{20}} = \sqrt{\frac{1}{4}} = \frac{1}{2}\]

Answer 4

You're using the pythagorean theorem to FIND the hypotenuse length of each segment of interest on both kites. Then you simplify the appropriate ratios of those lengths. Notice that BR/DB = 1/2

Answer 5

Try to understand what I did to find KE/YK

Answer 6

C ?

Answer 7

Correct

Answer 8

There's a way to figure it out without computing anything

Answer 9

Well, rather there's a way to figure it out using a combination of mental math and observation.

Answer 10

thank you!

Answer 11

If you consider slopes,
the slope of both BR and DB is 1/2
the slope of both KE and YK is 1/3
