What quadrilaterals has all angles are congruent?

Rectangles have all angles congruent,


Has 4 sides all sides are congruent opposite sides are parallel opposite sides are congruent and no angles are right angles?

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.


Can a rectangle be a square explain?

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.


What quadrilateral has all angles congruent?

The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.


All squares have four congruent sides. since rectangles are squaresall rectangles have four congruent sides yes or no and why?

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.


What quadrilaterals have congruent adjacent angles?

Rectangles or squares; both of these have only right angles, so all the angles are congruent.

Are all rectangles perpendicular?

Yes. The basic definition for a rectangle is 4 sides, four right angles(perpendicular), and opposite sides are congruent.


Are angles and sides of a parallelogram congruent?

In all parallelograms, opposite angles and opposite sides are congruent. If all four sides are congruent, it's a rhombus. If all four angles are congruent, it's a rectangle. If all four sides and all four angles are congruent, it's a square.
