No. A rectangle is a parallelogram because all of its sides are parallel, but a parallelogram is not a rectangle because it does not have all right angles.
It is a true statement to say that all rectangles are parallelograms. However, the statement that all parallelograms are rectangles is false. A parallelogram is a shape where its opposite sides are parallel to each other, including squares, hexagons, octagons, etc.

How do you prove that a parallelogram is a rectangle?
a rectangle has four right angles and opposite sides are all the same length This means that a parallelogram is not always a rectangle, but a rectangle is always a parallelogram, by definition.
If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle?
true.
What are the 4 quadrilaterals that have 2 pairs of parallel sides?
Parallelogram, rectangle, rhombus and square.Parallelogram, rectangle, rhombus and square.Parallelogram, rectangle, rhombus and square.Parallelogram, rectangle, rhombus and square.
What parallelogram can be inscribed in a circle?
if a parallelogram is inscribed in a circle it is always a rectangle...............
Which quadrilaterals have supplementary consecutive angles?
An equilateral quadrilateral which would include a square.
Is every parallelogram is also a rectangle?
No. Most parallelograms are not rectangles. But every rectangle is a parallelogram.
Is every parellelogram a rectangle?
No. Every parallelogram is not a rectangle but every rectangle is a parallelogram.
Is every parllelogram a rectangle?
No, but every rectangle is a parallelogram.
Is a parrallelogram a rectangle?
Yes, a rectangle is a special case of a parallelogram, where each of the 4 angles = 90°
Can a rectangle not be a parallogram?
No, it can't not be. Every rectangle is a parallelogram.
Can every rectangle be a parallelogram?
Well, a rectangle is defined as having two sets of parallel sides and four right angles, a parallelogram is defined as having two sets of parallel sides and two sets of supplementary angles. Therefor, a rectangle is always, by definition, a parallelogram. A parallelogram is not always a rectangle, but it can be.
Is th paralleloram a rhombus or a Rectangle?
I hope you know the definition of the parallelogram. i.e.,In geometry, a parallelogram is a quadrilateralwith two sets of parallel sides.so naturally rhombus and rectangle are special case of parallelogram. That means every rhombus is parallelogram similarly every rectangle is a parallelogram. But converse need not be true.So parallelogram not necessarily a rhombus or a rectangle.GMG.
What are three different names for a rectangle?
Every rectangle is also a parallelogram and a quadrilateral.
Is every rectangle parallelogram?
Yes, every rectangle is a parallelogram. Parallelograms are defined as a shape with opposite, but parallel sides. A rectangle is defined as a shape with 90 degree angles, 2 sets of parallel sides, and the opposite sides must be equal in length. Because the sides of any rectangle are parallel, any qualified rectangle is a parallelogram.
Is every parallelogram's a rectangle?
yes, as long as 2 sides are parallel, its a parallelogram.
Are consecutive angles in a parallelogram always congruent?
Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.
In what way is a rectangle similar to a parallelogram?
Every rectangle is a parallelogram. The description of a parallelogram is: -- a figure that lies in a single plane -- it has four sides -- opposite sides are parallel -- opposite sides have equal lengths -- alternate angles are equal Every rectangle satisfies this description.
