A plus sign (+) would be a pair of perpendicular line segments.
Yes, because if you draw a rectangle, there'll be at the top and the right side touch.
A right angle has one pair of perpendicular sides.
Any shape, other than a triangle can have a pair of perpendicular sides.
Hexagon.
An irregular hexagon.
Draw a right angle corner, then add 4 more sides that are NOT right angles...
Yes, they can exist.
A hexagon with only one pair of parellel sides
The question contradicts itself. A dodecagon need not have any perpendicular sides.
a pair of intersecting lines that are perpendicular
shape no pairs of perpendicular sides
A plus sign (+) would be a pair of perpendicular line segments.
It is possible for a hexagon to have one pair of parallel sides. A hexagon can have 0, 1, 2 or 3 pairs of parallel sides, and can have 0, 2, 3, 4, 5, or 6 parallel sides.
Yes, because if you draw a rectangle, there'll be at the top and the right side touch.
I suppose. All of a square's sides are perpendicular.
Draw a regular hexagon. Then take any vertex and move it towards or away from the opposite vertex, taking both arms of the angle. Another way of saying the same thing is stretch (or shrink) a pair of opposite sides.
