Use sin30=(x/8) where x is the altitude (the height) of the parallelogram. If p and q are the parallel lines, then they must follow the consecutive interior angle theorem, which means the angles must be supplementary. The diagonals are perpendicular bisectors of each other. use the diagram and information to complete the proof. Consecutive angles in a parallelogram will always sum to 180 degrees. She wondered if she could relate the angles formed by the bars to the concept of consecutive angles. These angles lie on the inside of the two parallel lines and on the same side of the transversal. Hence, it is proved that any two adjacent or consecutive angles of a parallelogram are supplementary. An interesting result is seen here. Therefore, it will become a rectangle. Let the smaller angle be 'x', the bigger angle be '8x'. For example, ∠A, ∠B are adjacent angles and ∠A = 90°, then: In the adjoining figure, ∠D = 85° and ∠B = (x+25) °, find the value of x. Strategy.
