Parallelograms:
1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines.
2.) opposite sides of a parallelogram are congruent
3.) diagonals bisect each other
4.)opposite angles are congruent
5.) consecutive angles are supp. *Remember that alternate interior angles are congruent.
To break it down in a better understanding way. 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. If the shape is a parallelogram then you can find the slope of its sides. if they are parallel to each other then it is a parallelogram. 2.) opposite sides of a parallelogram are congruent top and bottom sides are congruent. right and left sides are congruent. 3.) diagonals bisect each other When you draw a straight line from the top right corner to the bottom left corner and from the top left corner to the bottom right corner, the bisect each other or in better terms, the lines cut each other equaly in half. 4.)opposite angles are congruent just as the sides. 5.) consecutive angles are supp.
These angels produce a line. this line like all lines will add up to 180 degrees.
*Remember that alternate interior angles are congruent.

Is every rectangle is a parallelogram?
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.
Can you draw a parallelogram with one angle?
No, all the angles inside the parallelogram must add up to 360*. There are 4 corners, and if they are all the same then: 4n = 360 n = 90 Which means that the angle (n) will be 90*. If you draw this, it will be a square, which is not a parallelogram the parallelogram also has 6 angels jfhdgcgfhgjhghc i eat dicks
Can a parallelogram has consecutive sides congruent?
Yes. That would make all sides congruent; in this case, your parallelogram would be a rhombus.
Are all sides of a parallelogram sides angles congruent?
Not necessarily.
What are characteristics of a parallelogram?
A parallelogram has four sides and 2 pairs of parallel sides.
What describes a parallelogram?
5 vertices Another opinion: A parallelogram is a flat four-sided shape whose opposite sides are parallel. That's not a complete description of all the characteristics of a parallelogram, but that's all it takes to make sure that you've got one.
How many sides does a shape have to have to be a parallelogram?
A shape must have 4 sides in order to be a parallelogram (minus other defining characteristics a shape must have to be a parallelogram).
What characteristics help you classify a quadrilateral as a parallelogram and not a triangle?
Triangles have only three sides; all quadrilaterals, including parallelograms, have four.
What are 5 characteristics of a Quadrilateral?
Parallelogram quadrilateral trapezoid rectangle square
What are the characteristics of a parrallelogram?
The key characteristics of a parallelogram is that it is a quadrilateral with two pairs of parallel sides. Everything else follows for that.
Are rectangles parallelogram because their sides are parallel?
Yes all rectangles are parallelogram but all parallelogram cannot be rectangles.
What are two other names for rectangle?
I am not aware of any other names that take in all its characteristics. It is a parallelogram but that does not reuire its angles to be 90 degreesl etc.
What characteristics help classify a quadrilateral as a parallelogram and not a rectangle?
a rectangle has 4 right angles, a parallelogram has 2 acute angles and 2 obtuse angles
What is a parallelogram where all sides are equal?
A parallelogram where all sides are equal is a square.
Can a parallelogram have all congruent sides?
Yes.A parallelogram with all congruent sides is called a rhombus. A square is technically a parallelogram with all congruent sides as well.
How does a parallelogram relate to a rectangle?
A rectangle is a parallelogram but a parallelogram is not a rectangle. A rectangle needs all 90 degree angles but a parallelogram dosnt.
