volunteer	if u cut up the square into two..what do you get? ....what shape?	14,847	48	[]
student	rectangle	14,847	49	[]
volunteer	Thatat is one shape	14,847	50	[]
volunteer	say if u cut the square diagonally..what shape do u get?	14,847	51	[]
student	triangle	14,847	52	[]
volunteer	correct	14,847	53	[]
student	so how am i solving this question Triangle S has an area of 50 square units. Ben drew a scaled version of Triangle . He labeled it Triangle T (shown here). What scale factor did Ben use to go from Triangle S to Triangle T?	14,847	54	[ { "pii_type": "PERSON", "surrogate": "Ben", "start": 78, "end": 81 }, { "pii_type": "PERSON", "surrogate": "Ben", "start": 179, "end": 182 } ]
volunteer	please be patient	14,847	55	[]
student	ok	14,847	56	[]
volunteer	so two triangles make a square right?	14,847	57	[]
student	yes	14,847	58	[]
volunteer	so if u cut the area of a square into two...u get the following formula (a*b)/2...which is the formula for the area of a triangle	14,847	59	[]
student	h x w	14,847	60	[]
volunteer	so what now is the area of the triangle for the dimensions u gave me?	14,847	61	[]
student	50 for the first one	14,847	62	[]
volunteer	ok	14,847	63	[]
student	20 for the second im sure ?	14,847	64	[]
student	is that correct	14,847	65	[]
volunteer	no	14,847	66	[]
volunteer	using the formula I gave u ..what is the correct answer?	14,847	67	[]
student	it would be 10	14,847	68	[]
volunteer	exactly	14,847	69	[]
volunteer	very good	14,847	70	[]
student	oh	14,847	71	[]
student	so the sf would 10	14,847	72	[]
volunteer	now the bigger triangle has an area of 50 and the smaller triangle has an area of 10	14,847	73	[]
volunteer	how many times is bigger one bigger?	14,847	74	[]
student	no the smaller traingle should have a area of 20	14,847	75	[]
student	for area you do height times width which was 5 x 4	14,847	76	[]
student	there is no divison	14,847	77	[]
volunteer	why should the smaller triangle have an area of 20	14,847	78	[]
volunteer	remember, the formula for a triangle is (a*b)/2	14,847	79	[]
volunteer	5 x 4 is the area of a square	14,847	80	[]
volunteer	we don't want the area of a square	14,847	81	[]
student	no it isnt	14,847	82	[]
student	Triangle S has an area of 50 square units. Ben drew a scaled version of Triangle . He labeled it Triangle T (shown here). What scale factor did Ben use to go from Triangle S to Triangle T?	14,847	83	[ { "pii_type": "PERSON", "surrogate": "Ben", "start": 44, "end": 47 }, { "pii_type": "PERSON", "surrogate": "Ben", "start": 145, "end": 148 } ]
student	the picture i have	14,847	84	[]
student	states 5 x 4	14,847	85	[]
student	hello	14,847	86	[]
volunteer	yeah...	14,847	87	[]
volunteer	height is 5	14,847	88	[]
student	so what sf did Ben you	14,847	89	[ { "pii_type": "PERSON", "surrogate": "Ben", "start": 15, "end": 18 } ]
volunteer	width is 4?	14,847	90	[]
student	yes	14,847	91	[]
student	Ben use ?	14,847	92	[ { "pii_type": "PERSON", "surrogate": "Ben", "start": 0, "end": 3 } ]
volunteer	what is the area of the smaller triangle?	14,847	93	[]
student	the smaller triangle area is 20	14,847	94	[]
student	and the bigger triangle area is 50	14,847	95	[]
volunteer	height x width will give u the area for a nott a triangle	14,847	96	[]
volunteer	so u have to divide by 2	14,847	97	[]
student	oh mb u right	14,847	98	[]
student	so what the sf now	14,847	99	[]
volunteer	what is the area of the square that I drew?	14,847	100	[]
student	20	14,847	101	[]
student	but it is a triangle with the same numbers	14,847	102	[]
student	since we are dividing it it would be 10	14,847	103	[]
student	so the area of both shapes is 10,50	14,847	104	[]
volunteer	it doesn't mean they can have the same numbers	14,847	105	[]
student	ok	14,847	106	[]
volunteer	if I cut the square in half and ask you what the area of the shaded area is..what would it be???	14,847	107	[]
student	10	14,847	108	[]
volunteer	correct	14,847	109	[]
student	ok what is the scale factor Ben uses	14,847	110	[ { "pii_type": "PERSON", "surrogate": "Ben", "start": 28, "end": 31 } ]
volunteer	so we are looking at half a square which is a triangle	14,847	111	[]
student	yes	14,847	112	[]
volunteer	so how many times do I have to increase the smaller area to get to the bigger area	14,847	113	[]
volunteer	?	14,847	114	[]
student	for the 50 area triangle	14,847	115	[]
volunteer	yes	14,847	116	[]
volunteer	how many 10 (area triangles) fit in a 50 (area triangle)?	14,847	117	[]
student	5	14,847	118	[]
volunteer	yes	14,847	119	[]
volunteer	so your scaling factor would be 5	14,847	120	[]
volunteer	the bigger one is 5 times bigger than the smaller one	14,847	121	[]
volunteer	make sense?	14,847	122	[]
student	ok	14,847	123	[]
student	thx	14,847	124	[]
volunteer	your welcome..enjoy the rest of your day.ep up the good work	14,847	125	[]
volunteer	make sure you understand the difference between the area of a triangle and a square	14,847	126	[]
student	hello	14,899	0	[]
volunteer	Hello, how can I help you today?	14,899	1	[]
student	i have a homework assignment i need help on	14,899	2	[]
volunteer	sure put it up whenever ready	14,899	3	[]
volunteer	which ones do you need help with?	14,899	4	[]
student	all but first 1	14,899	5	[]
volunteer	everything except number 1?	14,899	6	[]
student	i meant lets start with one	14,899	7	[]
volunteer	ok then	14,899	8	[]
volunteer	do you know how to solve for slope?	14,899	9	[]
volunteer	y-two - y-one / x-two - x-one	14,899	10	[]
student	yes	14,899	11	[]
volunteer	ok then for number one lets label our points	14,899	12	[]
volunteer	2 is our x-one, 6 is our y-one. 5 is our x-two, and 1 is our y-two	14,899	13	[]
volunteer	so you would do 1 - 6 / 5 - 2	14,899	14	[]
volunteer	and our slope for number one would be -5/3	14,899	15	[]
student	it says simplify	14,899	16	[]
volunteer	yea so for number one thats all you can do. you cant simplify it anymore	14,899	17	[]
student	oh okay	14,899	18	[]
volunteer	should we move onto number 2?	14,899	19	[]
student	yes	14,899	20	[]
