Which posulate is this that proves they're congruent? i'm so confused.
side angle side (sas)
angle angle side (aas)
angle side angle (asa)

SAS

Step-by-step explanation:

<EDF and <GFH are corresponding angles, therefore must be congruent. <GHF and <EFD are also corresponding angles, so those must be congruent as well. Segments DF and FH are congruent as it's given. So yes, you're correct with the SAS there.

Step-by-step explanation:

<GHF and <EFD are corresponding angles and because of that they're congruent which then <EFD and <GFD are also corresponding sides so they're also congruent. And segments DF and FH are congruent as it's given.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
