yes not all of them are congruent i remember in fith grade i learned that
Rectangles have all angles congruent,
squares, rectangles, some rhombuses .... I'm not sure all angles can be congruent
Square and Rectangle
Yes.
Rectangles or squares; both of these have only right angles, so all the angles are congruent.
Rectangles have congruent adjacent angles.
rectangles
a rectangle has 4 right angles. A rhombus has four congruent sides. A square has four right angles and four congruent sides. All squares are rectangles because all rectangles have 4 right angles, and all squares have four right angles. But not all rectangles are squares because not all rectangles have congruent sides.
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
rectangles and squares have
A quadrilateral is a plane figure with four straight sides and does not necessarily have any congruent angles. Some quadrilaterals such as, squares, rectangles, rhombuses, and parallelograms do have congruent angles.
Some are regular and some are not . Regular rectangles are called squares. A square is a regular polygon because all of it's sides and angles are congruent. Oblong rectangles do not have all their sides congruent and so are not regular.
