Question

Similar Triangles

Attachment

Answer 1

Corresponding sides of similar triangles are in proportion.

The order of the vertices in the similarity statement

Tri ABC ~ Tri DEF tells you how to set up the extended proportion.

Answer 2

so cross multiply

Answer 3

AB/DE = BC/EF = AC/DF

Look at the diagram and fill in the numbers to see which two ratios to use.

5/DE = BC/12 = 8/15 --> @Ambbiiee Check to see if the side lengths are in the right place. If so, we can solve for BC right off the bat.

Answer 4

Oh, we are looking for DE.

Answer 5

5/DE = BC/12 = 8/15

so 5/DE = 8/15

Cross multiply and solve for DE. @Ambbiiee

Answer 6

8DE=75

Answer 7

DE = 75 divided by 8 and then DE = ?

Answer 8

9.375=DE

Answer 9

do i do the same for this one too? just cross multiply right ? @Directrix

Answer 10

Here, you are finding angles. Corresponding angles are congruent in similar triangles.

Answer 11

Which angle in Tri QPR corresponds to angle S in Tri TSV?

Answer 12

umm 6

Answer 13

I don't see an angle with a measure of 6.
You are looking at the SIDES of the triangles.
That is not what we are doing.
We are looking at the ANGLES of the triangles.
Look again and post what you think.

Answer 14

ohh 86

Answer 15

Vertex S corresponds to vertex P so yes, it is 86 degrees.

Answer 16

thanks
