It could be a right angle triangle
A right angle has one pair of perpendicular sides.
Yes, because if you draw a rectangle, there'll be at the top and the right side touch.
The first geometric shape that comes to mind with no perpendicular sides is a triangle.
I suppose. All of a square's sides are perpendicular.
Yes.
