Parallelograms are shapes that have four sides with two pairs of sides that are parallel. The four shapes that meet the requirements of a parallelogram are square, rectangle, rhombus, and rhomboid.
What are the 4 types of parallelograms?
- Rhombus (or diamond, rhomb, or lozenge) -- A parallelogram with four congruent sides.
- Rectangle -- A parallelogram with four congruent interior angles.
- Square -- A parallelogram with four congruent sides and four congruent interior angles.
Which shape is not a parallelogram?
A trapezium is the quadrilateral that is not a parallelogram as its two sides are not parallel.
Can a parallelogram have exactly 2 right angles?
A parallelogram is a quadrilateral with 2 pair of opposite sides parallel. ... A square is a special rectangle that has all four sides congruent. A kite has two consecutive sides congruent. The angle between these two sides could be a right angle, but there would only be one right angle in the kite.
Does a rhombus have 4 right angles?
If you have a rhombus with four equal interior angles, you have a square. A square is a special case of a rhombus, because it has four equal-length sides and goes above and beyond that to also have four right angles. Every square you see will be a rhombus, but not every rhombus you meet will be a square.

What is the most special type of parallelogram?
Rectangle. A rectangle is a special type of parallelogram which has all the properties of parallelogram along with some different properties. Each angle of a rectangle must be a right angle, i.e. of 90°.
Does a parallelogram have four right angles?
A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.
Which best describes the sides of a parallelogram?
In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
How do you tell if a polygon is a parallelogram?
- The opposite sides are parallel.
- The opposite sides are congruent.
- The opposite angles are congruent.
- Consecutive angles are supplementary (add up to 180-degrees).
- The diagonals bisect each other.
Can a parallelogram have 6 sides?
A parallelogon must have an even number of sides and opposite sides must be equal in length and parallel (hence the name). A less obvious corollary is that all parallelogons have either four or six sides; a four-sided parallelogon is called a parallelogram.
Are all angles in a parallelogram 90 degrees?
A Parallelogram can be defined as a quadrilateral whose two s sides are parallel to each other and all the four angles at the vertices are not 90 degrees or right angles, then the quadrilateral is called a parallelogram. The opposite sides of parallelogram are also equal in length.
Does a parallelogram have two 90 degree angles True or false?
True - A parallelogram has both pairs of opposite sides parallel and equal in length. A rectangle is a parallelogram with 4 right angles. Every rhombus is a rectangle. False - A rectangle must always have 4 right angles (90 degree angles).
What is the unique parallelogram?
Parallelograms have several characteristic properties that fall directly out of their definition as a quadrilateral with opposite pairs of parallel sides. ... opposite sides are congruent. opposite angles are congruent. adjacent angles are supplementary.
What are some real life examples of parallelogram?
- Properties of Parallelogram.
- Examples of Parallelogram. Tiles. Buildings. Roofs. Paper. Desks. Erasers. Solar Panels. Striped Pole. Steps of a Stair Case. Design on a Cardigan. Structure on the Fret Board of a Guitar.
What are 3 types of parallelograms?
Hence, a parallelogram is a quadrilateral that is bounded by parallel lines. It is a shape in which the opposite sides are parallel and equal. Parallelograms are classified into three main types: square, rectangle, and rhombus, and each of them has its own unique properties.
Has 4 angles that are 90 degrees?
A square is a quadrilateral with 4 right angles (90°). In a square, both pairs of opposite sides are parallel and equal in length.
What type of angles has a parallelogram?
A Parallelogram is a flat shape with opposite sides parallel and equal in length. Angle A and angle B add up to 180°, so they are supplementary angles. NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
Does a parallelogram bisect at 90 degrees?
The diagonals of a parallelogram bisect each other at right angles.
Do all parallelograms have 4 equal sides Yes or no?
Explanation: A Quadrilateral is only a 4 sided figure & has no specific features, whereas a Parallelogram is a 4 sided figure with opposite sides parallel and equal, opposite angles equal and adjacent angles in a linear pair. A Quadrilateral is not a Parallelogram. A Parallelogram is a Quadrilateral.
What is a six sided parallelogram?
In geometry, a hexagon (from Greek ἕξ, hex, meaning "six", and γωνία, gonía, meaning "corner, angle") is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.
Is Triangle a parallelogram?
A triangle is a parallelogram. This is never true. ... Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.
How do you identify a parallelogram?
- It has two pairs of parallel opposite sides.
- It has two pairs of equal opposite angles.
- It has two pairs of equal and parallel opposite sides.
- Its diagonals bisect each other.
What is the parallelogram side Theorem?
Theorem 1: In a parallelogram, the opposite sides are of equal length. Theorem 2: If the opposite sides in a quadrilateral are the same length, then the figure is a parallelogram. Theorem 3: A quadrilateral is a parallelogram if and only if the diagonals bisect each other.
