If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Opposite angles are congruent. Opposite sides are congruent. Consecutive angles are supplementary.

Parallelograms!


Properties shared by all parallelograms are also characteristics of rectangles?

yes


How many sides do 5 parallelograms have?

A parallelogram has four sides, so 5 parallelograms altogether have 4 * 5 = 20 sides


Do all parallelograms have diagonals which bisect?

Yes; all parallelograms have diagonals that bisect each other. Other properties of parallelograms are: * The opposite sides are congruent. * The opposite sides are parallel. * The opposite angles are congruent.


What is the properties of a parallelograms?

The base length of a parallelogram is larger than its width or its side.


How are trapezoids and parallelograms not related?

Trapezoids and parallelograms are distinct types of quadrilaterals that differ in their properties. A trapezoid is defined as having at least one pair of parallel sides, while a parallelogram has two pairs of parallel sides. This fundamental difference in the number of parallel sides means that all parallelograms are trapezoids, but not all trapezoids are parallelograms. Additionally, parallelograms have additional properties, such as opposite sides being equal in length and opposite angles being equal, which do not necessarily apply to all trapezoids.


Can you draw 5 different parallelograms?

yes you can


Are paralleograms a trapezoids?

Parallelograms and trapezoids have different geometrical properties but they are both 4 sided quadrilaterals.


What is true of rectangles that isn't true of parallelograms in general?

All rectangles have 90 degree angles and with parallelograms that does not always have to be the case. But no matter what in order for a parallelogram to be a rectangle the angles have to all be 90 degrees.Rectangles are special cases of parallelograms. They have all the properties of parallelograms, and in addition, all their internal angles are right-angles - 90° angles.


Can all rectangles and rhombi be classified as parallelogram?

Yes, all rectangles and rhombi can be classified as parallelograms. By definition, a parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Rectangles have right angles, and rhombi have equal side lengths, but both maintain the properties of parallelograms, including opposite sides being parallel. Thus, they are specific types of parallelograms with additional properties.


are any trapezoids parallelogram?

No because trapezoids have different properties to that of parallelograms but they are both 4 sided quadrilaterals.
