Parallelogram practice problems
A parallelogram is a quadrilateral that has two pairs of parallel sides.Properties of a parallelogram:
1. Opposite sides are parallel and of the same length.
2. Opposite angles are congruent.
3. Adjacent angles are supplementary (sum = 180°).
4. Diagonals bisect each other** (intersect in the middle).
Direction: Solve each problem carefully and show your solution in each item.
