what do you think it is?
clue: they are congruent.
I think it's D
you need to know your angle identities.
Vertically Opposite Angle is the clue
i think @nono266 can explain it to you.
angle QRP= angle SRT
http://www.regentsprep.org/Regents/math/geometry/GPB/theorems.htm take a look here
You can do it @jillina29
All I know is that it is not C, I tried that the first time because I thought the vertical angles was a side
hint: SSA is not a postulate.
oooh so it could be, B?!
Possibly, do you have reasons to support your answer?
I guess so....
@jilliana29 read the definitions of each from the site @nono266 Provided. http://www.regentsprep.org/Regents/math/geometry/GPB/theorems.htm\ Use to support Side-Side-Side (SSS) Congruence If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent. Side-Angle-Side (SAS) Congruence If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. Angle-Side-Angle (ASA) Congruence If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. Angle-Angle-Side (AAS) Congruence If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.
Because two of the options have "SSA" as a postulate, and you said how that is not a real postulate, also I tried C the first time and I did not get it right. So that narrows it down to B. @nono266
Well so you used process of elimination, i know it doesn't say to provide a reason but in future references make sure you have one. :)
Thank you! @nono266 @aric200 @arindameducationusc
that's what we're here for, good luck with your work
My pleasure @jillina29 Awesome work @nono266 and @aric200
aha not a problem @arindameducationusc :)
