What are 3 facts about parallelograms?
There are six important properties of parallelograms to know:
- Opposite sides are congruent (AB = DC).
- Opposite angels are congruent (D = B).
- Consecutive angles are supplementary (A + D = 180°).
- If one angle is right, then all angles are right.
- The diagonals of a parallelogram bisect each other.
What are some true facts about parallelograms?
In all Parallelogram’s opposite angles are equal to each other. Angles which are not opposite in the Parallelogram will add up to 180 degrees….Properties
- Opposite sides of parallelogram are parallel.
- Any line through the midpoint of a parallelogram bisects the area.
- Parallelograms are quadrilaterals.
What we know about a parallelogram?
A parallelogram is a two-dimensional quadrilateral — a shape that has four sides that intersect at four points, also known as vertices. The two opposite sides of a parallelogram are always parallel and congruent — or equal in length. Rectangles, squares and rhombuses are all examples of parallelograms.
What is special about a parallelogram?
A parallelogram is a two-dimensional quadrilateral with two pairs of parallel sides. The opposite angles and opposite sides of a parallelogram are congruent and the sum of its interior angles is 360°.
What is a parallelogram in real life?
A parallelogram is a four-sided figure with two pairs of parallel sides. Pencil erasers, clutch bags are parallelogram in real life. Even some of the strangest architectural buildings are shaped like a parallelogram.
Why are parallelograms important?
A parallelogram has four straight sides. Each of the two pair of opposing sides is of equal length and is parallel. The unique properties of the parallelogram have been applied extensively in industry to accurately transfer mechanical motion from one place to another.
Why is a parallelogram important?
Certainly. Precision bearings and slides immediately come to mind. However, the reed spring is less expensive, and there is no moving contact between its components.
What are real life examples of parallelograms?
11 Parallelogram Examples in Real Life

Why parallelograms are important in our lives?
Answer: A parallelogram has four straight sides. Each of the two pair of opposing sides is of equal length and is parallel. The unique properties of the parallelogram have been applied extensively in industry to accurately transfer mechanical motion from one place to another.

What are the rules for a parallelogram?
Properties of Parallelograms Explained
- Opposite sides are parallel.
- Opposite sides are congruent.
- Opposite angles are congruent.
- Same-Side interior angles (consecutive angles) are supplementary.
- Each diagonal of a parallelogram separates it into two congruent triangles.
- The diagonals of a parallelogram bisect each other.
What are the properties of a parallelogram?
Properties of parallelograms are as follows: i. Opposite sides of a parallelogram are equal. ii. Opposite angles of a parallelogram are equal. iii. Consecutive angles of a parallelogram add up to 180 degrees. iv.
Who was the first person to create a parallelogram?
3. History of Parallelograms. The concept of parallelograms was first explained by the Greek mathematician, Euclid. It forms an integral part of the Euclidian geometry put forth by him and has been explained in his book on geometry, The Elements.
Where does the word parallelogram come from in Greek?
The word “parallelogram” comes from the Greek word “parallelogrammon” ( bounded by parallel lines ). Rectangles, rhombuses, and squares are all parallelograms. As shown in the picture on the right, because triangles ABE and CDE are congruent (have the same shape and size),
Is the quadrilateral the same as the parallelogram?
This quadrilateral is the parallelogram. Apart from these, the parallelogram also finds its use in a famous English phrase “Think outside the quadrilateral parallelogram”, that means the same as to think out of the box. Here are a few facts about this shape. 1. What is a parallelogram?
