#1)The opposite sides of it are always parallel which is to say that they will never intersect.
#2)Its area must be twice the area of a triangle created by one of its diagonals.
#3)Its area is also equal to the magnitude of the vector cross product of two adjacent sides.
#4)Its perimeter of a parallelogram is 2(a + b) where a and b must be the lengths of adjacent sides.

How many right angles does a parallelogram?
A parallelogram doesn't need any right angles in order to be a parallelogram.If it has any, then it's a special kind of parallelogram, called a "rectangle".Note:The way the properties of a parallelogram work out,if it has one right angle, then it has four of them.
Is an isosceles trapezoid a parallelogram?
No, but they are both 4 sided quadrilaterals.
Why do all of the properties of a parallelogram apply to the rectangles?
Because a rectangle is a parallelogram.
What is a parallelogram with four 90 degre angles?
A parallelogram with four 90 degre angles is called rectangle.
How many sides does a parallelogram have?
Four of each.

Properties of a parallelogram?
A parallelogram has 2 pairs of parallel lines
Is an isosceles trapezoid a parallelogram?
No, but they are both 4 sided quadrilaterals.
What is the relationship between a parallelogram a rectangle and a square?
A square has all the properties of a rectangle and rhombus. (A square is always a rectangle.) A rectangle is not always a square but is always a parallelogram. A parallelogram is a quadrilateral (four sided figure) with both pairs of opposite sides are parallel. A rectangle is a quadrilateral with four right angles.
Why do all of the properties of a parallelogram apply to the rectangles?
Because a rectangle is a parallelogram.
What is a description of a parallelogram?
A parallelogram is a quadrilateral (4-sided figure) with both pairs of opposite sides parallel. That's usually the primary definition. There are properties common to all parallelograms: opposite sides are congruent, opposite angles are congruent, and diagonals bisect each other. Other special parallelograms have additional properties. A rectangle is a parallelogram with four right angles and its diagonals are congruent. A rhombus is a parallelogram with four congruent sides. Its diagonals are perpendicular and each diagonal bisects two angles of the rhombus. A square is a parallelogram as well. It has four right angles and four congruent sides, so it is also a rectangle and a rhombus. How's that for confusing???
Is a parallelogram is a square why?
Any four sided figures that satisfy the below properties is a parallelogram: 1. Any two opposite sides are parallel and congruent. 2. Any two opposite angles are congruent. Since the square satisfies those properties, then a square is a parallelogram.
What are three properties of a square?
rhombus,parallelogram
Which quadrilaterals have all the properties of a parallelogram?
Parallelograms!
What is a parallelogram shape with no sides?
By definition, a parallelogram has four sides. There is no other type of parallelogram.
Is a parallelogram always have 4 right angles?
A parallelogram does not have to be four right angles. A parallelogram is a four sided shape with two parallel lines.
What is parallelogram with four equal sides and four opposing angles?
A parallelogram with four equal sides is a rhombus.You are a rhombus quadrilateral.
