What is a parallelogram?

Parallelogram. (Jump to Area of a Parallelogram or Perimeter of a Parallelogram) A Parallelogram is a flat shape with opposite sides parallel and equal in length. Opposite angles are equal (angles A are the same, and angles B are the same) Angle A and angle B add up to 180°, so they are supplementary angles.

What should I look for when sketching a parallelogram?

Return to the list of Illustrative Math lessons. Parallelograms Let’s investigate the features and area of parallelograms. Illustrative Math Unit 6.1, Lesson 4 (printable worksheets) 4.1 - Features of a Parallelogram. Figures A, B, and C are parallelograms. Figures D, E, and F are not parallelograms. Study the examples and non-examples.

Are squares and rectangles parallelograms?

Parallelograms are quadrilaterals with two sets of parallel sides. Parallel lines are lines that never cross or intersect each other. Take a look! These are all parallelograms! It has the word parallel in it! Parallel means that two or more lines are side by side without ever touching each other. So, a parallelogram will have at least two sides ...

Figures A, B, and C are parallelograms. Figures D, E, and F are not parallelograms.

Why is Figure D not a parallelogram?

Squares and rectangles are also parallelograms as they have all these properties. Figure D is not a parallelogram because it does not have parallel opposite sides. Figure E is not a parallelogram because it has 6 sides.

How many square units are there in a blue rectangle?

The blue rectangle has an area of 3 × 6 = 18 square units. The rectangle made from the 2 right triangles also has an area of 18 square units. The total area of the parallelogram is 18 + 18 = 36 square units.

Do diagonals match up with each other?

Since the diagonals are parallel, the right triangles from decomposing the parallelogram will match up with each other, even when there is no grid to verify this. Note also that the diagonal length of 4.5 units was not necessary to find the area.

Can a parallelogram be decomposed?

We can decompose and rearrange a parallelogram to form a rectangle. The image below shows three ways to decompose and rearrange a parallelogram:

How many types of parallelograms are there?

There are three special types of a parallelogram.

Where does the term "parallelogram" come from?

The term ‘parallelogram’ is derived from Middle French ‘ parallélogramme’, Late Latin ‘parallelogrammum’ and Greek ‘parallelogrammon’ which means “bounded by parallel lines”.

Which side of a parallelogram is parallel to each other?

The opposite sides of a parallelogram are parallel to each other.

What type of quadrilateral has equal and parallel opposite sides?

A parallelogram is a special type of quadrilateral that has equal and parallel opposite sides.

How to identify parallelograms?

A parallelogram has two identifying properties.#N#A parallelogram has four straight sides.#N#The opposite sides of a parallelogram are parallel, and they have the same length. 1 A parallelogram has four straight sides. 2 The opposite sides of a parallelogram are parallel, and they have the same length.

What are the features of a parallelogram?

Here are the most important features of a parallelogram: Parallelograms must have four sides. If the shape you're looking at doesn't have four sides, it's not a parallelogram! For example, both the rhombus and the rectangle have four sides, so they're both parallelograms. Parallelograms have two opposite parallel sides.

How to tell if a parallelogram is a straight line?

It has top and bottom sides that are parallel, meaning those sides are straight lines that go in the same direction as each other. If you look at the right and left sides of your front door, it's the same thing: two parallel sides. Go take a look at your front door and you will see a parallelogram!

How many straight sides does the park have?

That is, the shape of the park has four straight sides, such that opposite sides are parallel and have the same length.

Is a square a parallelogram?

A square is a square, but it's also a parallelogram! A parallelogram is a shape with four sides, and the sides opposite each other are parallel. This means that they go in the same direction and will never cross over each other, like the rails on train tracks! 2:30. You must c C reate an account to continue watching.

Is a baseball diamond a parallelogram?

Therefore, a baseball diamond satisfies the properties of a parallelogram, so it is a parallelogram. Answers will vary, but the reasoning should explain how each example satisfies the properties of a parallelogram.

Is a notebook a parallelogram?

Answers: A piece of notebook paper is a rectangle with four straight sides, such that opposite sides are parallel and have the same length, so a piece of notebook paper satisfies the properties of a parallelogram. Hence, a piece of notebook paper is a parallelogram.

Parallelogram Definition

A parallelogram can be defined as the shape whose opposite sides are parallel and equal in length.

Overview of Parallelogram

A parallelogram is a quadrilateral that has two pairs of parallel sides. Also, the opposite sides are equal in length. In real-world, the parallelogram shape can be seen in a table-top, desktop, front and back view of building blocks, and the front and back view of the famous building of Hamburg, Germany, commonly known as Dockland, and many more.

Line of symmetry of a Parallelogram

A line that divides a figure into two identical halves is called the line of symmetry. A parallelogram ABCD is shown below:

Real-life Examples of a Parallelogram

The real-life example of a parallelogram is the top view of the eraser as shown below, where the opposite sides are parallel and equal in length.

What is a parallelogram?

A parallelogram is a flat shape with four straight, connected sides so that opposite sides are congruent and parallel. This means a parallelogram is a plane figure, a closed shape, and a quadrilateral. You can have almost all of these qualities and still not have a parallelogram. If the four sides do not connect at their endpoints, ...

How to identify parallelograms?

Using the properties of diagonals, sides, and angles, you can always identify parallelograms. You need not go through all four identifying properties.

What are the properties of a parallelogram?

One interesting property of a parallelogram is that its two diagonals bisect each other (cut each other in half). Another property is that each diagonal forms two congruent triangles inside the parallelogram .

How many sides does a parallelogram have?

You have learned that a parallelogram is a closed, plane figure with four sides. It is a quadrilateral with two pairs of parallel, congruent sides. Its four interior angles add to 360° 360 ° and any two adjacent angles are supplementary, meaning they add to 180° 180 °. Opposite (non-adjacent) angles are congruent.

How to tell if a quadrilateral is a parallelogram?

You can use proof theorems about a plane, closed quadrilateral to discover if it is a parallelogram: If the quadrilateral has bisecting diagonals, it is a parallelogram. If the quadrilateral has two pairs of opposite, congruent sides , it is a parallelogram.

What is a rectangle that leans over?

Take a rectangle and push either its left or ride side so it leans over; you have a parallelogram. A rectangle is a type of parallelogram.

What are the interior angles of a parallelogram?

The interior angles are ∠W ∠ W, ∠X ∠ X, ∠Y ∠ Y, and ∠Z ∠ Z. The opposite angles are congruent. In our parallelogram, that means ∠W = ∠Y ∠ W = ∠ Y and ∠X = ∠Z ∠ X = ∠ Z.
