then these sides should also be equal. There's a property like this, so by this we can say that AB will be equal to CD and that we have this angle which, which is equal so we have this angle here, the side here
4,385
502
[]
volunteer
uh
4,385
503
[]
volunteer
and we also have this side here
4,385
504
[]
volunteer
but we don't have any criteria called a
4,385
505
[]
volunteer
ASSR S S A
4,385
506
[]
volunteer
So, how is it working?
4,385
507
[]
volunteer
Mm
4,385
508
[]
volunteer
Well, you can turn your mic on if you wanna say.
4,385
509
[]
student
My mic is not working since the mic itself is not in best condition do its not labeling me
4,385
510
[]
student
abling
4,385
511
[]
volunteer
OK, OK. Oh, no problem.
4,385
512
[]
volunteer
No problem
4,385
513
[]
student
hmm we can say that like
4,385
514
[]
volunteer
Yeah, maybe we can say like that.
4,385
515
[]
volunteer
But uh the, this is still strange that if we have a very clear tra solution like this, why is uh
4,385
516
[]
volunteer
it not accepting this as a solution. It's, it's still strange, don't you think so?
4,385
517
[]
volunteer
Because this solution is very clear
4,385
518
[]
volunteer
um, but it's fine. OK. Um, we can move to the next question if you want.
4,385
519
[]
student
It wont let me move on until I complete it
4,385
520
[]
volunteer
Uh, so you told me that
4,385
521
[]
volunteer
I
4,385
522
[]
volunteer
you just used this property and it worked so, so isn't your uh question solved now?
4,385
523
[]
volunteer
I, I thought you saw that
4,385
524
[]
volunteer
OK, so we still need to think about this, so.
4,385
525
[]
volunteer
um OK
4,385
526
[]
student
This is how far I am
4,385
527
[]
volunteer
OK, OK
4,385
528
[]
student
and 6 is wrong
4,385
529
[]
volunteer
So you use reflexive property and then you used vertical angles congruency. So you can, you can say uh that is exactly what I'm saying.
4,385
530
[]
volunteer
that
4,385
531
[]
volunteer
uh, you can't use these properties here.
4,385
532
[]
volunteer
because they won't give you anything.
4,385
533
[]
volunteer
I mean, this is correct your statement is also correct. Your reasoning is also correct, but how will you prove that these triangles are congruent by these statements.
4,385
534
[]
volunteer
You're using AC congruent to AC.
4,385
535
[]
volunteer
OK. But uh what will you do from that? How will you prove that these two triangles are congruent.
4,385
536
[]
student
Im not sur
4,385
537
[]
student
sure
4,385
538
[]
volunteer
Yeah, exactly. So, yeah, these won't work. Yeah. We need to think of something else. OK. Let, let's just think again, right?
4,385
539
[]
volunteer
So
4,385
540
[]
volunteer
hm
4,385
541
[]
student
up until 5 the app says its right. Not for fully solving but true
4,385
542
[]
volunteer
uh doctor Fully solving, but true.
4,385
543
[]
student
so that's how far I got even tho some statements don't help
4,385
544
[]
volunteer
up until 5. Yeah, it's, it's true. I won't say that any of these statements are false, but these won't help you to uh get to your final
4,385
545
[]
volunteer
uh, congruency statement, right?
4,385
546
[]
volunteer
Because just by these, how can you say that your triangles are congruent by SSS.
4,385
547
[]
volunteer
How are you even applying that?
4,385
548
[]
student
yes. and also I still can
4,385
549
[]
volunteer
You haven't proved that above, right?
4,385
550
[]
student
change 6
4,385
551
[]
student
as it is default
4,385
552
[]
volunteer
You can change 6, yeah. Oh
4,385
553
[]
volunteer
but
4,385
554
[]
student
I can also make it an angle
4,385
555
[]
volunteer
maybe we, we first need to prove that angle BAD is 90 degrees.
4,385
556
[]
volunteer
even though it's given that BC is perpendicular to AD. Maybe we need to prove that the BAD is 90 degree because if we see this notice over here, it says that at least one of the two angles you mentioned is not a proven right angle. It doesn't say that you're those angles are not 90 degrees, says that they aren't proven...
4,385
557
[]
volunteer
What do you think
4,385
558
[]
student
so perpendicular angles form right angles
4,385
559
[]
volunteer
Yeah, I know that
4,385
560
[]
volunteer
Uh, but we need to explain this to the
4,385
561
[]
student
saying that BAD is a right angle
4,385
562
[]
volunteer
a pro the the solution, right?
4,385
563
[]
student
ded that
4,385
564
[]
volunteer
Perpendicular lines form
4,385
565
[]
volunteer
a right angles.
4,385
566
[]
volunteer
Yes
4,385
567
[]
volunteer
Um
4,385
568
[]
volunteer
OK, then, uh, maybe try using this first add this as a statement that angle that angle be AD is 90 degrees and then add this as a statement that I will CDA is 90 degree, and then, and then add the statement.
4,385
569
[]
volunteer
and then say substitution as a reasoning for this
4,385
570
[]
volunteer
Maybe it will work this way.
4,385
571
[]
student
I did the reasoning for both as perpendicular angles and it worked
4,385
572
[]
volunteer
As perpendicular angles and it worked?
4,385
573
[]
volunteer
OK
4,385
574
[]
volunteer
And now use uh this
4,385
575
[]
volunteer
this statement, uh, with the reasoning substitution.
4,385
576
[]
student
substitution still does not work
4,385
577
[]
volunteer
Substitution doesn't work. Oh my God. Um.
4,385
578
[]
volunteer
uh, can you share the screenshot with me?
4,385
579
[]
volunteer
Do you substitution for congruency, there must be a third angle which has already been proved
4,385
580
[]
volunteer
to be congruent to both BAD and ADC.
4,385
581
[]
volunteer
BAD
4,385
582
[]
volunteer
P A D and ADC.
4,385
583
[]
volunteer
Oh
4,385
584
[]
volunteer
Uh, OK, so, uh, do one thing that remove this statement and also remove this one, also remove this one
4,385
585
[]
volunteer
Uh, these are not useful.
4,385
586
[]
student
once it excepts it you cant remove. but even tho they don't help, it wont effect
4,385
587
[]
volunteer
OK, it won't help, it won't affect. OK, OK. Then it's fine.
4,385
588
[]
volunteer
Um
4,385
589
[]
student
as long as the data base sees that I complely proved
4,385
590
[]
volunteer
OK
4,385
591
[]
student
its on IXL math
4,385
592
[ { "pii_type": "LOCATION", "surrogate": "IXL", "start": 7, "end": 10 } ]
volunteer
I got you
4,385
593
[]
volunteer
Um, OK, so
4,385
594
[]
volunteer
uh, are you trying to explain something to me?
4,385
595
[]
student
yes I am examining it now
4,385
596
[]
volunteer
You can write on the, OK, OK, you're examining. Oh, it's fine. OK.
4,385
597
[]
volunteer
You can also write something on the whiteboard if you want.
4,385
598
[]
volunteer
So
4,385
599
[]
volunteer
OK, so
4,385
600
[]
volunteer
we said that
4,385
