Question

is the following statement true or false? two lines in a plane are either parallel or perpendicular. true false

Explanation:

Two lines in a plane can intersect at any angle (not just 90 degrees for perpendicular) or be parallel. For example, lines with slopes 1 and 2 intersect at an angle that is not 90 degrees, so they are neither parallel nor perpendicular. Thus the statement is false.

Answer:

false
