Question

select the most precise and correct definition of perpendicular lines from among those that are given. choose 1 answer. a two lines are perpendicular if they meet at one point and one of the angles at their point of intersection is a right angle. b two lines are perpendicular if they have opposite slopes. c two distinct lines are perpendicular if they are as far from being parallel as possible.

Explanation:

Perpendicular lines intersect at a point and form a 90 - degree (right) angle. Opposite slopes are a property for non - vertical perpendicular lines in a coordinate plane but not the most general definition. The "as far from being parallel as possible" is a non - precise description.

Answer:

A. Two lines are perpendicular if they meet at one point and one of the angles at their point of intersection is a right angle.
