Question

The sides of a rectangle can be created by four lines whose slopes are 1,−1,1 and −1 respectively. True or false?

Answer 1

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 2

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.
