Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
You have to know the slopes of both lines. -- Take the two slopes. -- The lines are perpendicular if (one slope) = -1/(the other slope), or the product of the slopes equals to -1.
Are perpendicular to one another.
I believe they have Negative Slopes as stated by my Geometry Book. "Perpendicular Lines Have Slopes Which Are Negative ___"
Yes, as long as the negative slopes are both equal.
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.

When the perpendicular lines are horizontal and vertical.
The slopes of two perpendicular lines are negative inverses of each other. In other words, the two slopes when multiplied together equal -1.
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
Are perpendicular.
Are perpendicular to one another.
Is it possible for two lines with positive slopes to be perpendicular?
I believe they have Negative Slopes as stated by my Geometry Book. "Perpendicular Lines Have Slopes Which Are Negative ___"
Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.
