volunteer	So yes, this was basically the whole thing and	4,385	702	[]
student	thank you! I will write it down!	4,385	703	[]
volunteer	and this was the angle that we used here, this angle we used this angle we use this angle, and this was the site.	4,385	704	[]
volunteer	Yeah, you can write it down.	4,385	705	[]
volunteer	Uh, do you have any more questions, by the way?	4,385	706	[]
volunteer	I can help you	4,385	707	[]
student	yes I do ! I have a few more like this one\	4,385	708	[]
volunteer	OK, OK, we can work on those together.	4,385	709	[]
volunteer	Uh, by the way, uh, was the solution clear to you? I know we can be confused the whole thing a lot.	4,385	710	[]
volunteer	uh, but is this clear at the end?	4,385	711	[]
student	yes!	4,385	712	[]
volunteer	OK, perfect.	4,385	713	[]
volunteer	Uh, just write this down and then you are done, just let me know and then they'll move on to the next question.	4,385	714	[]
student	okay Im ready!	4,385	715	[]
volunteer	Hi, OK	4,385	716	[]
volunteer	Uh, just, uh, share the next question, we can work on it together.	4,385	717	[]
volunteer	I'm sorry	4,385	718	[]
volunteer	Oh, OK	4,385	719	[]
volunteer	So AD is	4,385	720	[]
volunteer	congruent to AB, OK. And AB is	4,385	721	[]
volunteer	perpendicular to BC. So basically, we know that this angle is 90 degrees.	4,385	722	[]
volunteer	and AD is perpendicular to CD. So this angle is also 90 degrees.	4,385	723	[]
volunteer	Prove that triangle A, B, C is congruent to ADC.	4,385	724	[]
volunteer	OK, so that's again think of the five criterias of congruency that we have. SSS SAS	4,385	725	[]
volunteer	A A S	4,385	726	[]
volunteer	A S A	4,385	727	[]
volunteer	and RHS	4,385	728	[]
volunteer	So, uh, what do you think? Can we use SSS? We don't have 3 sides.	4,385	729	[]
volunteer	uh, which are equal. So let's first write down what do we know? We know that AB is equal to Ad because this is given, right?	4,385	730	[]
volunteer	And we also know that we first, we first write that anger A, B, C is equal to 90 degree directly write that angle ABC is equal to angle ADC as we did in the last question because that whole concept would be wrong, right? So we'll first write this and the reasoning for this will be that uh perpendicular lines,	4,385	731	[]
volunteer	make	4,385	732	[]
volunteer	right angles	4,385	733	[]
volunteer	And similarly, we'll say that angle ADC is also 90 degree.	4,385	734	[]
volunteer	and from this, then we will say that angle A, B, C equals angle A.	4,385	735	[]
volunteer	ADC	4,385	736	[]
volunteer	because right angles are congruent.	4,385	737	[]
volunteer	I'm sorry	4,385	738	[]
volunteer	OK, so, uh	4,385	739	[]
volunteer	now let's think of the next steps. So we know that one angle is equal at this	4,385	740	[]
volunteer	here we have our angle	4,385	741	[]
volunteer	This is our side. This is another side. We also know that this site is common in both so by reflexive property, we can say that	4,385	742	[]
volunteer	AC is congruent to	4,385	743	[]
volunteer	AC	4,385	744	[]
volunteer	by reflexive property.	4,385	745	[]
volunteer	So we have our, another side here.	4,385	746	[]
volunteer	OK	4,385	747	[]
volunteer	Um	4,385	748	[]
volunteer	so we can't use SSS here because we don't have 3 sites. We also can't use essays. We we might think that we can use SAS because we have two sides and we have one angle.	4,385	749	[]
volunteer	Uh, but this angle should be included angle, which means they should be between both of these sides. So if I'm taking these two sides, then this should have been our angle, but our angle is this, so we also can't use this one. If you use AAS	4,385	750	[]
volunteer	we can use AAS because we don't have two uncles, so this is also wrong	4,385	751	[]
volunteer	Again, we don't have two angles, so we can't use this. If you think about RHS.	4,385	752	[]
volunteer	or, or do you also call that HL?	4,385	753	[]
volunteer	Uh	4,385	754	[]
student	I call it HL	4,385	755	[]
student	hypotenuse leg	4,385	756	[]
volunteer	OK, OK. You call it HL then I'll, I'll also call it the same. I'm sorry.	4,385	757	[]
volunteer	A hypoten leg. OK.	4,385	758	[]
volunteer	Uh, so basically, I'm from another country, so I kind of don't know the term terminologies that you use in the UK, so I'm sorry for that. I'm sorry for the inconvenience, uh, yeah.	4,385	759	[ { "pii_type": "LOCATION", "surrogate": "UK", "start": 111, "end": 113 } ]
student	its okay!	4,385	760	[]
volunteer	By HL	4,385	761	[]
volunteer	So how, how are we using HL here HL is basically hypertonous and leg. So we have, so, uh, what does hypoten use? It's basically the site opposite to the right angle in a triangle. So if	4,385	762	[]
volunteer	if this is our chronicle	4,385	763	[]
volunteer	right	4,385	764	[]
volunteer	And this is a right angle to the side opposite to this is this side, right? And we know that this side is equal in both. We prove that by reflexive property. So we have the hyperterus equal about the neck	4,385	765	[]
volunteer	This is our leg, right? We have this equal in both the trigals, and we also have, uh, this, so by HL we can say that our triangle.	4,385	766	[]
volunteer	ABC	4,385	767	[]
volunteer	is congruent to triangle	4,385	768	[]
volunteer	ADC	4,385	769	[]
volunteer	Um, is this clear? Just, just try this and tell me if it's working or not.	4,385	770	[]
volunteer	I think it should work now.	4,385	771	[]
student	everything works up until we got to HL	4,385	772	[]
volunteer	So HL is not working.	4,385	773	[]
volunteer	Um	4,385	774	[]
volunteer	why is that you not working?	4,385	775	[]
volunteer	I think it should work because we have already proved that	4,385	776	[]
volunteer	AB is equal to AD, AD is equal to AD because this is given in our question.	4,385	777	[]
volunteer	and C is equal to AC because it's reflexive and this is the hypertenus.	4,385	778	[]
volunteer	This is the leg, so I think it should work.	4,385	779	[]
volunteer	Uh, can you show me the error message that you're getting.	4,385	780	[]
volunteer	You cannot use HL theorem yet, because you have not proved that each of these triangles is a right triangle.	4,385	781	[]
volunteer	So you also need to prove that these triangles are right triangle.	4,385	782	[]
volunteer	Oh	4,385	783	[]
volunteer	uh, how can you do that?	4,385	784	[]
volunteer	Basically, uh, if you have one right angle in your triangle. So it is a, it is a right triangle, right?	4,385	785	[]
volunteer	So	4,385	786	[]
volunteer	uh, can you think of another statement which you can use, maybe something like	4,385	787	[]
volunteer	um triangle A, B, C	4,385	788	[]
volunteer	is a right triangle, a statement like that	4,385	789	[]
volunteer	and then the reason will be because because angle ABC is 90 degree.	4,385	790	[]
volunteer	Uh, just try something like that if it's possible.	4,385	791	[]
volunteer	Uh, just let me know if you are able to try or not, and then we can think of something else.	4,385	792	[]
student	it says it has already been proved	4,385	793	[]
volunteer	It, it has already been proved.	4,385	794	[]
volunteer	Uh, but in the notice we get that these triangle are because we haven't proved yet that that each of these tiles is a right triangle.	4,385	795	[]
volunteer	Uh, what is the problem?	4,385	796	[]
volunteer	So for the thing that you are saying that it has already been proved, uh, can you share a screenshot of that.	4,385	797	[]
volunteer	of like what you entered and what was the notice that you got.	4,385	798	[]
volunteer	OK, so, no, don't use this as your reason.	4,385	799	[]
volunteer	No, don't use this. So what you are using, the reason you're using is that an angle congruent to a right angle is a right angle.	4,385	800	[]
volunteer	So you are basically saying that if we know that angle is 90 degrees, OK?	4,385	801	[]
