"The product of the slopes of segment JK and segment J prime K is −1; therefore, lines f and g are perpendicular."
Step-by-step explanation:
it literally says it on my chart because i have to find step 5 not 6.
Step 1segment KL is parallel to the y-axis, and segment JL is parallel to the x-axis.
Step 2ΔJKL was rotated 90° clockwise to create ΔJ'KL'. Point K did not change position, so it remains point K. Therefore, ΔJKL ≅ ΔJ'KL'.
Step 3segment K L prime is perpendicular to the y-axis, and segment J prime L prime is perpendicular to the x-axis.
Step 4segment JK lies on line f and has a slope of 3.
Step 5?
Step 6The product of the slopes of segment JK and segment J prime K is −1; therefore, lines f and g are perpendicular.
