volunteer	centroid --> mid point	12,941	25	[]
volunteer	Orthocenter --> Perpendicular	12,941	26	[]
volunteer	circumcenter --> circle	12,941	27	[]
student	Yeah my teacher said it and I was still confused but I understand it	12,941	28	[]
student	I was confused on memorizing it	12,941	29	[]
student	So the circumcenter is	12,941	30	[]
volunteer	I don't think you should try to remember this	12,941	31	[]
student	Yeah I think your right	12,941	32	[]
volunteer	do you want to work on these 3 problems now?	12,941	33	[]
student	Sure	12,941	34	[]
volunteer	oka	12,941	35	[]
volunteer	okay.	12,941	36	[]
student	Circumcenter is perpendicular bisect or	12,941	37	[]
student	So like the midpoint and slope of the line	12,941	38	[]
volunteer	yes!	12,941	39	[]
student	So I’ll just solve it out first then	12,941	40	[]
volunteer	let's find the equation for two perpendicular bisectors	12,941	41	[]
student	Okay	12,941	42	[]
student	So I’ll write it out?	12,941	43	[]
volunteer	you can work on a piece of paper, we can then compare numbers	12,941	44	[]
student	Yeah sure	12,941	45	[]
student	Sorry I just started	12,941	46	[]
volunteer	no problem. I am also kind of slow	12,941	47	[]
student	Wait I think I did it wrong	12,941	48	[]
student	I got 14 for x	12,941	49	[]
volunteer	is it possible for x to be that big?	12,941	50	[]
volunteer	the maximum of x is 6 for the 3 vertices	12,941	51	[]
student	I did this in class with someone else and got it right	12,941	52	[]
volunteer	let me work on the board	12,941	53	[]
volunteer	to make sure	12,941	54	[]
student	I know the answer was def not 14	12,941	55	[]
volunteer	exactly	12,941	56	[]
volunteer	let me graph it so you can get a sense on what x can be	12,941	57	[]
volunteer	I will work on the algebra on the board	12,941	58	[]
volunteer	does this make sense?	12,941	59	[]
student	I got the same slope but for the mid point I got (2,3)	12,941	60	[]
student	Let me check	12,941	61	[]
volunteer	ok	12,941	62	[]
student	Yeah it makes sense	12,941	63	[]
volunteer	let's continue	12,941	64	[]
student	Yeah	12,941	65	[]
volunteer	I used the point-slope form	12,941	66	[]
student	Yeah same	12,941	67	[]
student	That’s how my teacher taught it	12,941	68	[]
volunteer	great	12,941	69	[]
volunteer	next, let's do AC?	12,941	70	[]
student	I did cb	12,941	71	[]
volunteer	no problem. I will be cb as well	12,941	72	[]
student	Oh yeah I got the slope wrong	12,941	73	[]
volunteer	I see	12,941	74	[]
volunteer	it is very easy to make a mistake	12,941	75	[]
student	Wait is it suppose to be positive	12,941	76	[]
volunteer	you are right!!!	12,941	77	[]
volunteer	so the slope for the perp bisector will be -2	12,941	78	[]
student	Yeah	12,941	79	[]
volunteer	how do you solve this system of equations?	12,941	80	[]
student	You simpfly it and make it equal to each other	12,941	81	[]
volunteer	great	12,941	82	[]
volunteer	yes!	12,941	83	[]
volunteer	we can also subtract one from the other to get rid of y	12,941	84	[]
student	Oh yeah	12,941	85	[]
volunteer	this is what I got	12,941	86	[]
student	Let me solve it out	12,941	87	[]
volunteer	ok	12,941	88	[]
student	Do you have to distribute?	12,941	89	[]
volunteer	I did	12,941	90	[]
student	Yeah it is 19/7	12,941	91	[]
volunteer	great	12,941	92	[]
volunteer	now you can compute y	12,941	93	[]
student	Idk why it’s not letting me write	12,941	94	[]
student	Oh nvm	12,941	95	[]
volunteer	that's what I got as well	12,941	96	[]
volunteer	so it should be right.	12,941	97	[]
student	Yeah i have the answer key	12,941	98	[]
volunteer	cool	12,941	99	[]
volunteer	you want to work on the 2nd one?	12,941	100	[]
student	Yeah	12,941	101	[]
volunteer	ok. let's work on paper first	12,941	102	[]
volunteer	and then compare numbers	12,941	103	[]
student	Sure	12,941	104	[]
student	I got x right	12,941	105	[]
volunteer	great	12,941	106	[]
volunteer	13/4?	12,941	107	[]
student	Yeah	12,941	108	[]
volunteer	great. y is relatively easy	12,941	109	[]
volunteer	once x is correct.	12,941	110	[]
student	Oh yeah	12,941	111	[]
student	11/2	12,941	112	[]
volunteer	yes	12,941	113	[]
volunteer	you are good!	12,941	114	[]
volunteer	for the centroid, there is actually a simple formula	12,941	115	[]
student	Omg really	12,941	116	[]
volunteer	x=1/3(x1+x2+x3)	12,941	117	[]
volunteer	y=1/3(y1+y2+y3)	12,941	118	[]
volunteer	:)	12,941	119	[]
student	I will use that to check my work	12,941	120	[]
volunteer	yes please	12,941	121	[]
student	thank you so much :)	12,941	122	[]
volunteer	you are very welcome.	12,941	123	[]
volunteer	I actually have to drop, but I think you are in great shape.	12,941	124	[]
