Question

Triangle ABC is similar to triangle DEF. Using the image below, prove that parallel lines have the same slope. You must show all of your work to receive credit.

Answer 1

Add the image!

Answer 2

Slope is rise over run. The smaller triangle the sloper is from point F to point D, 3 up three across, so the slope=1

The larger on is from point C to point A which is 6 up and 6 across. So slope=1

Both triangles have a slope of 1

Answer 3

is that the answer

Answer 4

yes that is your answer, prove that they have the same slope, which I did.
