Adjacent sides are perpendicular. Opposite sides are parallel.
In a square adjacent sides are perpendicular to each other and opposite sides are parallel to each other.
square
The perpendicular adjacent sides in the triangle would be 3 sides. It is the basically horizonstal line next to a vertical line(perpendicular) if it was parallel adjacent then only two side of triangle /\ <-- parallel
Yes. Adjacent sides in a cube are perpendicular and planes that are perpendicular to the same plane are parallel.
parallel
no, because parallel is opposite to perpendicular
perpendicular
Yes. Squares only contain 90 degree angles, so all sides are perpendicular to the adjacent sides and parallel to the opposite one.
the opposite of parallel lines are Perpendicular. A perpendicular angle or line is where there is a 90 degree on each and every side.
The opposite sides are parallel to each other
the diagonal in a paralleogram is not equal but the diagonals in the rectangle are congruent this is because the opposite sides of a parallelogram and rectangle are same parallel to each other but the adjacent sides of a parallelogram is not perpendicular where as the adjacent sides of rectangle is perpendicular to each other.
