Answer:
True
Step-by-step explanation:
Perpendicular lines are lines whose angles are 90 degrees
Lines that are perpendicular have slopes that multiply to -1
-1* 1 = -1
Lines that are parallel have the same slope
We have 2 lines that are parallel with 1 and 1
And 2 lines that are parallel with -1 and -1
These 2 sets of lines are perpendicular to each other so they make 90 degree angles
Answer:
it is true
Step-by-step explanation:
because perpendicular lines are 90 degrees and the slope can be coorinated as 1,-11 and -1 respectively.
