square
-- Opposite sides are parallel. -- Opposite sides are equal. -- All four sides are equal. -- Adjacent sides are equal. -- Adjacent angles are supplementary. -- Opposite angles are equal. -- Diagonals are perpendicular. -- Interior angles sum to two straight angles. -- Exterior angles sum to two straight angles.
All squares have TWO SETS of opposite, parallel sides. A square is a parallelogram with 4 equal sides and 4 equal angles (right angles) of which adjacent sides are perpendicular. The related parallelogram, the rhombus, or "diamond" shape, also has 4 equal sides, but no right angles, where opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).
An octagon can have both perpendicular and parallel lines, depending on its specific configuration. In a regular octagon, opposite sides are parallel, while the angles between adjacent sides can create perpendicular lines in certain contexts. However, in an irregular octagon, the arrangement of sides and angles can vary widely, leading to different relationships between lines.
Only if the angles formed are right angles otherwise they form vertical opposite equal angles
There are many characteristics of a rhombus. Every rhombus is a parallelogram, so it has all the characteristics of one: opposite sides are parallel, adjacent angles are supplementary, and the diagonals bisect each other. Additionally, there are two other characteristics that apply to rhombuses: the opposite angles are congruent and the diagonals are perpendicular.

Yes. Squares only contain 90 degree angles, so all sides are perpendicular to the adjacent sides and parallel to the opposite one.

A quadrilateral with 4 right angles and opposite sides that are parallel can be either a rectangle if the adjacent sides are of different length or a square if the adjacent sides are of the same length.
All quadrilaterals apart from rectangles. Even parallelograms have adjacent angles that are not equal.

None!!!! Every face is angles to its adjacent and opposite faces.
Yes, adjacent angles are supplementary; however, opposite angles are not.
yes it is A trapizium has no right angles therefore there are no perpendicular.* * * * *Nonsense! A trapezium can have two adjacent angles which are right angles.
It is not possible for a quadrilateral in Euclidean plane geometry to have no equal angles and still have its opposite sides parallel.It's possible for a quadrilateral to have no equal angles and two of its sides parallel (opposite ones, obviously; adjacent sides can't possibly be parallel). That would be a trapezoid.
