Interior consecutive angles in a parallelogram can be seen in the following image: The pair of consecutive angles for the parallelogram can be named as (∠A,∠D) (∠ A, ∠ D), (∠A,∠B) (∠ A, ∠ B), (∠C,∠D) (∠ C, ∠ D), and (∠C,∠B) (∠ C, ∠ B). Proof: parallelograms consecutive angles are supplementary. Answer by richwmiller (17219) ( Show Source ): You can put this solution on YOUR website! One such property is that the diagonals of a rectangle are congruent. This is a result of the line BD being a transversal of the parallel lines AB and CD. An important property of parallelograms is that consecutive angles are supplementary, or that the sum of their measures is 180˚. A + D = D + C. So, A = C. Similarly, B = D. A = C and B = D. Hence Proved ! B. The diagonals bisect each other.

If a pair of adjacent sides of a parallelogram is equal, it must be a rhombus or a square. There are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). It is known that two consecutive angles of a parallelogram are supplementary to each other. Opposite angels are congruent (D = B). I will state t… Consecutive angles are supplementary. So if opposite sides of a quadrilateral are parallel, then the quadrilateral is a parallelogram. The parallelogram has the following properties: Opposite sides are parallel by definition. What do you think the sum of consecutive angles is? Thus, two consecutive angles are (30 + 60)°, (2 × 30 + 30)° i.e. Proof: Opposite angles of parallelogram congruent, Proof: Opposite Angles of a Parallelogram are Equal.
