Put 2 lines on the perpendicular sides and put 1 line for the parallel sides
A capital "H."
The slope of the perpendicular is -(1/2) .
For the line 2x + y = 8 , the slope equals ( -2 ) so the required slope of the line which is perpendicular to it is equal to (+1/2 )
-3
Any line that is not parallel to the given lines. The transversal that contains the shortest distance between the two parallel lines, is perpendicular to them.
The line y = 2x If you put it into the form y = mx + b, you have y = 2x + 0 so the slope is 2. Lines parallel to that line have the same slope, 2. Perpendicular lines have slopes that multiply to -1. The slope of a perpendicular line to a line of slope 2 would be -1/2.

The shortest distance between 2 parallel lines is a perpendicular drawn between 2 parallel lines the diagram shows it clearly 1 parallel line ------------------------------------|-------------------------------------------------------------------- | | | the vertical line is the shortest distance | | ------------------------------------|------------------------------------------------------------------- 2nd parallel line
A pentagon can have 0, 1 or 2 pairs of parallel lines. It can have 0 to 4 lines perpendicular to an adjacent line. A rhombus must have two pairs of parallel lines and none of them may be perpendicular to any other.

If: y = 2/5x+10 then the perpendicular slope is -5/2x or -2.5x
