Yes.
yes, they are all 90 degress.
Rectangles, of which squares are a special case.
The shape described is a rhombus. A rhombus has four sides that are all congruent, and its opposite sides are parallel. Additionally, while opposite angles are equal, none of the angles are right angles. This geometric figure maintains these properties, distinguishing it from other quadrilaterals like rectangles or squares.
the opposite angles are congruent
Rectangles or squares; both of these have only right angles, so all the angles are congruent.
Square and Rectangle
yes, they are all 90 degress.
Rectangles (including squares).
A square and a rectangle have opposite equal 90 degree angles. A parallelogram and a rhombus have 2 opposite equal acute angles and 2 opposite equal obtuse angles.

Rectangles have congruent adjacent angles.
square and a rectangle
No, not all rectangles have four congruent sides. While all squares are rectangles (since they meet the definition of having four right angles and opposite sides that are equal), rectangles in general can have sides of different lengths. Therefore, rectangles can have two pairs of equal sides but do not necessarily have four congruent sides like squares do.
