What are the four properties of a parallelogram?

What are the Four Important Properties of a Parallelogram? 1 The opposite sides are equal. 2 The opposite angles are equal. 3 The diagonals are equal. 4 The opposite angles are equal. More

How are the diagonals of a parallelogram supplementary?

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.

How are the opposite sides of a parallelogram equal?

The opposite sides of a parallelogram are equal in measurement and they are parallel to each other. The opposite angles of a parallelogram are equal. The sum of interior angles of a parallelogram is equal to 360°. The consecutive angles of a parallelogram should be supplementary (180°).

Are there any theorems about parallelograms in math?

Theorem 1: In a Parallelogram the Opposite Sides Are Equal. This means, in a parallelogram, the opposite sides are equal. Given: ABCD is a parallelogram. To Prove: The opposite sides are equal, AB=CD, and BC=AD. Proof: In parallelogram ABCB, compare triangles ABC and CDA.

What’s the difference between a parallelogram and a rhombus?

Difference Between Parallelogram and Rhombus Parallelogram Rhombus A quadrilateral that has its opposite si A quadrilateral that has all its sides c Diagonals bisect each other Diagonals bisect each other at 90 degree Opposite angles are of equal measure All four angles are of equal measure

What are the interior angles of a parallelogram?

Angles of Parallelogram. A parallelogram is a flat 2d shape which has four angles. The opposite interior angles are equal. The angles on the same side of the transversal are supplementary, that means they add up to 180 degrees. Hence, the sum of the interior angles of a parallelogram is 360 degrees.
