I disagree with you on 2 and 3

I just guessed on 2 I don't know what they mean

like what is that rule

For Q2, do you know what SAS is short for?

icalibearBest ResponseYou've already chosen the best response.2
no what is it short fot? thats probably why i cant get it

In 2 they just want to you to choose which triangle can be proven by using "Side Angle Side" and that angle must be between those two sides.

phiBest ResponseYou've already chosen the best response.2
As aroub says, you want (in both triangles) Side Angle Side in that order

icalibearBest ResponseYou've already chosen the best response.2
oh so the answer would be G) because it's then angle
 one year ago

phiBest ResponseYou've already chosen the best response.2
both triangles share the same side. so that is side. the next angle is 90 degrees, so you have the angle, then the 3rd side is marked congruent so G is SAS

ok and for number 3 what did i do wrong there?

phiBest ResponseYou've already chosen the best response.2
for Q3, you could look for SSS or SAS. which one of the choices will give you one or the other?
 one year ago

icalibearBest ResponseYou've already chosen the best response.2
umm A), because it's SAS?

Are you reading what I am ? A says PN=SQ those are sides. the picture gives you 2 sides. You need the 3rd (unmarked) sides to be =, or you need the angle between the marked sides to be equal (SAS means in that order)
 one year ago

icalibearBest ResponseYou've already chosen the best response.2
you would need <O and <S then because those are the unmarked angles that are equal?
 one year ago

phiBest ResponseYou've already chosen the best response.2
and angle O is between the 2 marked sides and S is between the 2 marked sides. It is not angle P= angle S because P is not between the marked sides

oh got confused there ok so its D
 one year ago

phiBest ResponseYou've already chosen the best response.2
B says ON=QR but in the picture ON is marked with 2 dashes. ON matches the 2 dashes on OS. You would want the unmarked sides to be = (NP=QR) then you could use SSS. But the answer is D

icalibearBest ResponseYou've already chosen the best response.2
ok thanks i just got confused there and for the last one is the answer H)? since its the same thing as before?
 one year ago

phiBest ResponseYou've already chosen the best response.2
choice H would give you angle side angle in the first triangle what does angle F give you? (remember, you "read" the triangle side angle side angle and so on. If a side or angle is unmarked just say ? what does angle F give you?
 one year ago

icalibearBest ResponseYou've already chosen the best response.2
it looks like sideangleangleside
 one year ago

icalibearBest ResponseYou've already chosen the best response.2
oh i thought you said option F hold on
 one year ago

icalibearBest ResponseYou've already chosen the best response.2
f gives you anglesideangle
 one year ago

phiBest ResponseYou've already chosen the best response.2
there are 3 sides and 3 angles. If we start with side DE, it is marked, so we can say side angle E is marked. so now we have side angle side EF is not marked so we have sideangle? angle F is marked (per choosing option H) so sideangle?angle now side FD is unmarked: sideangle?angle? finally, angle D is unmarked: sideangle?angle?? now we need in the exact order sideangleside but we do not have that, because we have ? in between.
 one year ago

icalibearBest ResponseYou've already chosen the best response.2
so to prove it we have to find ? which has to be side
 one year ago

icalibearBest ResponseYou've already chosen the best response.2
the answer would be F) because thats sideanglesideangle
 one year ago

phiBest ResponseYou've already chosen the best response.2
that would work. sideangle?angle?? ^  if we can match this side (side EF) with the other triangle, we could use sideangleside
 one year ago

icalibearBest ResponseYou've already chosen the best response.2
to match it with the other triangle you could flip EF and have it congruent then you would have sas
 one year ago

phiBest ResponseYou've already chosen the best response.2
yes, side EF matched with HI gives SAS.

ok got it. thanks so much>!

phiBest ResponseYou've already chosen the best response.2
OK. I hope it is not too confusing. A little practice helps.

icalibearBest ResponseYou've already chosen the best response.2
yeah definitely i just didn't know how i as suppose to read it or what sas stood for or anything so this definitely helped
