http://gyazo.com/2787ca3ca620af066010322bb7912ae5 I want to say this is isosceles because of the -10 but the other part isn't the same so would it be scalene. here are the options. right isosceles scalene equilateral
use the distance formula which says that distance between two points (x1,y1) and (x2,y2) is\[\sqrt{(x2-x1)^2+(y2-y1)^2}\]
|dw:1352555726378:dw|
But there is 3 parts how would I use the distance formula for that?
|dw:1352555791543:dw|
|dw:1352555946747:dw|
so AC=AB but not =BC SO ISOSCELES:)
Ah thank you so much for explaining it. I did it myself when you showed the first part. I was confused didn't know I used the distance formula too.
no prob sometime it just happened:)
