negative reciprocal slopes
No, because a regular polygon should have sides of equal length. But the adjacent sides of a recentangle can have different lengths.
Rectangles have congruent adjacent angles.
A rectangle is an oblong, as its sides are not equal. A square has equal sides. Therefore, a square is not a rectangle. A rhombus is a parallelogram with oblique angles and equal sides.
no. Not necessarily. A rhombus is a parallelogram with equal adjacent sides. Gererally, though they will be unequal.
sure why not
No but a square does
A square is a rectangle whose adjacent sides are equal.
Adjacent sides are also equal.
Adjacent sides of a rectangle are perpendicular.
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.
A square is a rectangle, but a rectangle isn't necessarily a square. A square can be thought of as a "special" rectangle, where all sides are equal. The similarity is that all rectangles have 4 angles each of 90o However a Square has 4 sides equal length while a Rectangle has 4 sides with opposite sides of equal length. The clever observer will note that the adjacent sides of a square are equal while the adjacent sides of a rectangle may or may not be equal. yes it is
adjacent sides of a rectangle are the sides that are next to each other. :D
Yes unless a specific sort of Rectangle !
