Perpendicular lines intercept each other at right angles which is 90 degrees
Spheres do not have any perpendicular lines.
Perpendicular: No Parallel: Yes, two pairs.
They are simply four pairs of perpendicular lines. There is nothing in the question to suggest there is anything more than that to them.
a regular hexagon
Perpendicular to what? Four pairs cannot be mutually perpendicular unless you go into hyperspace.
How many pairs of perpendicular sides does this figure have?
no
a squareof course
Can have no pairs or one pair...
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
Yes.
