## 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.
