## What are the 6 properties of a parallelogram?

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.

### Do parallelograms always equal 180?

Therefore, the sum of any two adjacent angles of a parallelogram is equal to 180°. Hence, it is proved that any two adjacent or consecutive angles of a parallelogram are supplementary.

**Can a parallelogram have 4 right angles?**

A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals.

**Can a parallelogram have 90 degree angles?**

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. If one angle is 90 degrees, then all other angles are also 90 degrees.

## Do parallelograms have 90 degree angles?

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.

### Do all parallelograms have 4 equal sides Yes or no?

A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides. A square has two pairs of parallel sides, four right angles, and all four sides are equal.

**Do parallelograms equal 360?**

Parallelograms have angles totalling 360 degrees, but also have matching pairs of angles at the ends of diagonals.

**Do all parallelograms have 4 right angles?**

Right Angles in Parallelograms In a parallelogram, if one of the angles is a right angle, all four angles must be right angles. If a four-sided figure has one right angle and at least one angle of a different measure, it is not a parallelogram; it is a trapezoid.
