Hello!
The answer is: A square.
Why?
The quadrilateral is a square since:
- It has four right angles, squares have four right angles (90°), giving a total of 360° if you sum all of them.
- It has four equal sides, squares have four sides of equal length.
- It has two pairs of opposite sides that are parallel, if we look for a side of a square, we will find an opposite side which is parallel, so, squares have two pairs of opposite sides that are parallel.
Have a nice day!
