It need not have any. A right triangular prism has 12 pairs but could have 14.
Octagons have no perpendicular lines.
It has 2 pairs.
An octahedron has 7 perpendicular lines.
There are four perpendicular lines in a rectangle
Can have no pairs or one pair...
How many pairs of perpendicular sides does this figure have?
4
2
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
10, A decagon has a maximum of five pairs of perpendicular lines, and a maximum of 5 parallel lines. however, this isn't in black and white it can have no pairs of line either perpendicular or parallel. know write the answer clearly
A parallelogram has 2 pairs of parallel lines and in the form of a rectangle it has 2 pairs of parallel lines and 4 perpendicular lines that meet at each of its corners at right angles.
10, A decagon has a maximum of five pairs of perpendicular lines, and a maximum of 5 parallel lines. however, this isn't in black and white it can have no pairs of line either perpendicular or parallel
One. There's actually two...
Oh, dude, a heptagon has like a bazillion pairs of perpendicular lines... just kidding! It actually has 14 pairs of perpendicular lines. So, like, if you ever need to find perpendicular lines in a heptagon, you've got plenty to choose from.

At least two pairs: they form the outer rectangle which represents the "universe".
