Triangle ABC is similar to triangle DEF. Using the image below, prove that lines BC and EF have the same slope. You must show all of your work to receive credit.
Triangle ABC and DEF are shown. A is at negative 2, 1. B is at negative 2, 4. C is at 1, 1. D is at 4, 2. E is at 4, 4. F is at 6, 2.

Best ResponseYou've already chosen the best response.2to find the slope of BC, you divide the length of AB over the length of AC basically slope = rise/run the slope of BC is negative since it runs downhill as you move from left to right

Best ResponseYou've already chosen the best response.0oh ok so the length of AB would be 3 right ? and then the length of AC would be 3 to right ?

Best ResponseYou've already chosen the best response.0ok so the length of DE would be 2 and then DF would 2 as well right and when i divide them both i get 1

Best ResponseYou've already chosen the best response.2make that result negative since the line EF goes downhill as you read left to right slope of EF = 1

Best ResponseYou've already chosen the best response.0oh ok so would this be the answer ??

Best ResponseYou've already chosen the best response.2yes you have shown that slope of BC = slope of EF
