When is the product of the slopes of two perpendicular lines not equal to -1?
When the perpendicular lines are horizontal and vertical.
What is the symbol for perpendicular lines?
It is a vertical line touching a horizontal line
What is a pattern of horizontal and vertical lines that cross each other at right angles?
perpendicular lines
Which shape has parallel lines but no perpendicular lines?
A rhombus has parallel lines but no perpendicular lines.
Can two lines be parellel perpendicular and intersecting at the same time?
No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.

Can two horizontal lines be perpendicular to each other?
No.
Are all lines perpendicular to a horizontal plane vertical?
Yes.

perpendicular lines
Are lines of latitude perpendicular parallel or intersecting?
Lines of latitude are horizontal and run parallel to the poles
Are the perpendicular line segments of a letter the straight lines?
Not necessarily. The horizontal and diagonal lines are also straight lines.
Motion perpendicular to earth's surface is what kind of motion?
Motion Perpendicular to the ground is called horizontal motion.
What is the definition of a horizontal line?
Horizontal lines are straight curves that typically runs from left to right across the page, usually sharing the same y-coordinate. Horizontal lines are perpendicular to vertical lines.
Does an isosceles trapezium have any perpendicular lines?
In its normal orientation the parallel sides of a trapezium are horizontal. In that case it will have no perpendicular lines. But turn the figure through 90 degrees and it has two!In its normal orientation the parallel sides of a trapezium are horizontal. In that case it will have no perpendicular lines.

What is horizontal markings?
Horizontal markings are markings (such as painted or etched lines) that are horizontal (or parallel to the ground).
How many sets of perpendicular lines are in a right triangle?
There is only one set of perpendicular lines in a right triangle; the horizontal line and the vertical line that make it 90 degrees.
