yes they are, they have 4 sides and 2 parallel sides
What else can I help you with?
Which common quadrilaterals have two lines of symmetry?
Rhombuses and Rectangles
Which three quadrilaterals have perpendicular diagonals?
Squares, Rectangles, and Rhombuses.
Do quadrilaterals that have 2 lines of symmetry?
Parallelogram (if it is a rectangle), Rectangles and Rhombuses (if they are not also a square)
What are the examples of quadrilaterals and non-examples of quadrilaterals?
Quadrilaterals are things with four sides, like squares, rectangles, diamonds, trapezoids, rhombuses. Anything that doesn't have four sides (an infinite list) is a non-example of a quadrilateral.
Is a square a rombus?
yes all squares are rhombuses but not all rhombuses are squares
Which of the quadrilaterals are rhombuses?
Only rhombuses are rhombuses. Some rhombuses are squares.
What are the irregular quadrilaterals?
Rhombuses, rectangles, kites, parallelograms, and trapezoids are all irregular quadrilaterals.
Are all squaresrhombirectangle a parallelogram?
All squares, rhombuses, rectangles and parallelograms are 4 sided quadrilaterals.
What are quadrilaterals that aren't rectangles?
Squares, parallelograms, rhombuses, and trapezoids are quadrilaterals that are not rectangles.
Why are all rhombuses parelllelagrams?
Because they are both four sided quadrilaterals with opposite parallel sides.
What are the 3 quadrilaterals?
well, there are rectangles, squares, rhombuses,
Which common quadrilaterals have two lines of symmetry?
Rhombuses and Rectangles
What quadrilaterals bisect at 90 degrees?
Squares and rhombuses (rhombi?)
Which three quadrilaterals have obtuse angles?
parallelograms, rhombuses, & hexagons
Which three quadrilaterals have perpendicular diagonals?
Squares, Rectangles, and Rhombuses.
What quadrilaterals have parallel sides and perpendicular diagonals?
They are squares and rhombuses
What quadrilaterals have all four angles congruent?
squares, rectangles, some rhombuses .... I'm not sure all angles can be congruent
