Best ResponseYou've already chosen the best response.0I disagree with you on 2 and 3

Best ResponseYou've already chosen the best response.2I just guessed on 2 I don't know what they mean

Best ResponseYou've already chosen the best response.2like what is that rule

Best ResponseYou've already chosen the best response.2For Q2, do you know what SAS is short for?

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

Best ResponseYou've already chosen the best response.0In 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.

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

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

phi

Best ResponseYou've already chosen the best response.2both 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

Best ResponseYou've already chosen the best response.2ok and for number 3 what did i do wrong there?

phi

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

icalibear

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

phi

Best ResponseYou've already chosen the best response.2Are 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)

icalibear

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

phi

Best ResponseYou've already chosen the best response.2and 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

Best ResponseYou've already chosen the best response.2oh got confused there ok so its D

phi

Best ResponseYou've already chosen the best response.2B 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

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

phi

Best ResponseYou've already chosen the best response.2choice 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?

Best ResponseYou've already chosen the best response.2it looks like sideangleangleside

icalibear

Best ResponseYou've already chosen the best response.2oh i thought you said option F hold on

icalibear

Best ResponseYou've already chosen the best response.2f gives you anglesideangle

phi

Best ResponseYou've already chosen the best response.2there 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.

icalibear

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

icalibear

Best ResponseYou've already chosen the best response.2the answer would be F) because thats sideanglesideangle

phi

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

icalibear

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

phi

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

Best ResponseYou've already chosen the best response.2ok got it. thanks so much>!

phi

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

icalibear

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