What are all quadrilaterals with congruent diagonals?
Parallelograms or isosceles trapezium.
What are the shapes that have at least one pair of parallel lines?
All i know is a Trapezium parallelograms
Are trapezium a parallelograms?
No. The trapezium has only one pair of parallel sides. A parallelogram needs two pair.
What 4 sided shape has 2 parrallel sides?
A square , a rectangle , a rhombus , in fact all the parallelograms have two parallel sides . Also a trapezium also has two parallel sides , which means one pair of parallel sides . The parallelograms have four parallel sides.
Differences between parallelograms and trapezoids?
Parallelograms have two pairs of parallel sides, trapezium only one. Both pairs of opposite sides of a parallelogram must be equal, in a trapezium at most one pair can be. Opposite angles of a parallelogram must be equal, not so for a trapezium.
Is every property of parallelograms also a property of all rectangles?
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
Which are the quadrilaterals that have their opposite sides equal?
Parallelograms (and their special cases), isosceles trapezium.
Some parallelograms are squares?
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.
Are some parallolegrams trapezoid?
No, they cannot be. All parallelograms must have two pairs of parallel sides whereas a trapezium can have only one such pair.
Can a parallelogram also be a rectangle?
Some parallelograms are rectangles; all rectangles are parallelograms.
All rectangles are also .?
parallelograms.
Are all parallelograms also square?
no
