Web24 jan. 2024 · Complete/full angles: An angle of \ (360^ {\circ}\) is known as a complete or full angle. It is equivalent to two straight angles or four right angles. A complete angle and a zero angle are represented in the same way, but there is one difference: the degree of rotation. Let us look at an example of a complete angle. WebIt is a special case of a parallelogram that has four congruent sides and four right angles. A square is also a rectangle because it has two sets of parallel sides and four right angles. A square is also a parallelogram because its opposite sides are parallel.
A parallelogram has rotational symmetry of order 2 (through 180°) (or order 4 if a square). If it also has exactly two lines of reflectional symmetry then it must be a rhombus or an oblong (a non-square rectangle). If it has four lines of reflectional symmetry, it is a square.
