True or false. if triangle abc~triangle def, then ab/de=ca/fd

True

Step-by-step explanation:

For two triangles to be similar, their corresponding sides have to be proportionate.

That means that AB/CA = DE/FD, AB/BC = DE/EF, and CA/BC = FD/EF.

The corollary to the means-extremes theorem shows that the proportion will remain true even if the numerator of one ratio switches with the denominator of the other ratio.

That means that AB/DE = CA/FD, in this situation.

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
