can you help me @GabeBae
xapproachesinfinity
  • xapproachesinfinity
4 is ASA
xapproachesinfinity
  • xapproachesinfinity
first we were given angle congruency and a side
thehollywoodstud
  • thehollywoodstud
and 5 is cpctc
xapproachesinfinity
  • xapproachesinfinity
then 3 they proved another angle congruency so in 4 we have angle side angle gives two congruent triangles
thehollywoodstud
  • thehollywoodstud
and can u also help me with this one too?
xapproachesinfinity
  • xapproachesinfinity
well for 5 you have congruent triangle therefore all respective sides are congruent
thehollywoodstud
  • thehollywoodstud
so am i right then ?
xapproachesinfinity
  • xapproachesinfinity
what is cpctc?
xapproachesinfinity
  • xapproachesinfinity
sorry not familiar with this abreviation
thehollywoodstud
  • thehollywoodstud
Corresponding parts of congruent triangles are congruent
thehollywoodstud
  • thehollywoodstud
does that help?
xapproachesinfinity
  • xapproachesinfinity
yes good same as i said
xapproachesinfinity
  • xapproachesinfinity
thanks :)
thehollywoodstud
  • thehollywoodstud
ok so how about this one ?
xapproachesinfinity
  • xapproachesinfinity
okay for the next one 2 we know that all right angles are congruent 90 degrees
xapproachesinfinity
  • xapproachesinfinity
3 is given
thehollywoodstud
  • thehollywoodstud
ok so is that what i put ?
xapproachesinfinity
  • xapproachesinfinity
yea
xapproachesinfinity
  • xapproachesinfinity
4 DSH congruent to DST
xapproachesinfinity
  • xapproachesinfinity
angles of course
thehollywoodstud
  • thehollywoodstud
ok so 5 is ?
xapproachesinfinity
  • xapproachesinfinity
5 is SAS
thehollywoodstud
  • thehollywoodstud
ok yeah that makes sense...
xapproachesinfinity
  • xapproachesinfinity
no sorry AAS
thehollywoodstud
  • thehollywoodstud
so i have two more i need help with
xapproachesinfinity
  • xapproachesinfinity
ok
thehollywoodstud
  • thehollywoodstud
here is the first one
xapproachesinfinity
  • xapproachesinfinity
Do you agree that we have isos triangle
thehollywoodstud
  • thehollywoodstud
yes
thehollywoodstud
  • thehollywoodstud
,not all of the sums of the angles are equal
xapproachesinfinity
  • xapproachesinfinity
good! do you agree that angles at the base are congruent
thehollywoodstud
  • thehollywoodstud
yes
xapproachesinfinity
  • xapproachesinfinity
then do you see that x+x+38=180
thehollywoodstud
  • thehollywoodstud
yes
xapproachesinfinity
  • xapproachesinfinity
so 2x=180-38
xapproachesinfinity
  • xapproachesinfinity
x=?
thehollywoodstud
  • thehollywoodstud
71?
xapproachesinfinity
  • xapproachesinfinity
correct
thehollywoodstud
  • thehollywoodstud
so is that my answer?
xapproachesinfinity
  • xapproachesinfinity
yes for sure! we started with recognizing two identical sides that told us we have isos triangle then we employed the fact that isos triangles have two congruent angles at the base then we used the fact of angles of a triangle 180 then it is reasonable what our solution is x=71
thehollywoodstud
  • thehollywoodstud
so last one ?

thehollywoodstud
  • thehollywoodstud
i know we have right angles
xapproachesinfinity
  • xapproachesinfinity
yes there are! but i'm going to not look at as right triangles (drawing can deceive us ) first let's look at the big triangle
thehollywoodstud
  • thehollywoodstud
ok
xapproachesinfinity
  • xapproachesinfinity
we are given an isos triangle again
thehollywoodstud
  • thehollywoodstud
ok
xapproachesinfinity
  • xapproachesinfinity
sorry website crash we are also given angle C=47 so B=47 then 47+47+2y=180
xapproachesinfinity
  • xapproachesinfinity
y=43
xapproachesinfinity
  • xapproachesinfinity
now focus on x x+43+47=180
xapproachesinfinity
  • xapproachesinfinity
im looking at triangle ABD
xapproachesinfinity
  • xapproachesinfinity
so it is x=90 as we thought
thehollywoodstud
  • thehollywoodstud
ok
xapproachesinfinity
  • xapproachesinfinity
you can go with the fact angle bisector in isos triangle is perpendicular to the base
xapproachesinfinity
  • xapproachesinfinity
if you one a different method
thehollywoodstud
  • thehollywoodstud
ok
xapproachesinfinity
  • xapproachesinfinity
so x=90 then look for y
xapproachesinfinity
  • xapproachesinfinity
read about angle bisector
