Answer: perpendicular</h3>
====================================================
Work Shown:
Use the slope formula to find the slope of line AB
m = (y2-y1)/(x2-x1)
m = (f-0)/(e-0)
m = f/e
Let p = f/e so we can compare the slope later
---------------
Use the slope formula to find the slope of line CD
m = (y2-y1)/(x2-x1)
m = (0-e)/(f-0)
m = -e/f
Let q = -e/f so we can compare the slope later
---------------
We have
- p = f/e which is the slope of AB
- q = -e/f which is the slope of CD
Multiply the values of p and q
p*q = (f/e)*(-e/f) = (f(-e))/(ef) = (-ef)/(ef) = -1
since p*q = -1, this means the lines AB and CD are perpendicular. They form a 90 degree angle.
