  • Has diagonals which bisects each other.

2. Parallelogram

  • Its pairs of opposite sides are congruent.

3. Parallelogram

  • 105° + 75° is equal to 180°, therefore its consecutive angles are supplementary and is making this quadrilateral a parallelogram.

4. Parallelogram

  • It has two pairs of parallel sides

5. Not a parallelogram

  • It has no supplementary angles, congruent opposite sides, pairs of parallel sides, and diagonals which bisects each other.
