Question

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

Answer 1

Get the slope of the 2 line segments using the endpoints.

Answer 2

I have know idea how to do that

\[\huge m=\frac{y_2-y_1}{x_2-x_1}\]

Answer 4

Find the slopes of both and if the slopes are equal, then the lines will be parallel...

Slope of LMN = LM/MN
Slope of QRS = QR/RS

Answer 5

ok thank you
