The length of EC = 6, while the length of DC = 7.
What are the properties of a parallelogram?
A parallelogram can be defined as a type of quadrilateral that has the following functions:
- The opposite sides are equal.
- The opposite sides are parallel.
- The opposite angles are equal.
- The adjacent angles add up to 180⁰
- The diagonals bisect each other.
The length of EC would be =6 because the bisector of the parallelogram divided line AC into two equal parts.
The length of DC would be = 7 because opposite sides are equal in a parallelogram.
