Any shape with straight edges can have perpendicular edges.
The first geometric shape that comes to mind with no perpendicular sides is a triangle.
The question does not make any sense. "Adjacent" means next to. A shape cannot be next to itself, and if it is next to another shape, then you have two shapes. "perpendicular" means at right angles (or 90 degrees) to. Again, a shape cannot be perpendicular to itself.

Any shape, other than a triangle can have a pair of perpendicular sides.
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
A cuboid
a circle
check your selves!

Two-dimensional shapes made with perpendicular lines include (but are not limited to) right-triangles, rectangles, octagons, and dodecagons. Three-dimensional shapes made with perpendicular lines include (but are not limited to) cubes, octahedrons, cuboctahedrons, and icosahedrons.
