Question

What is the most specific name for the quadrilateral on number #28?

Answer 1

the most specific is a square bc all the angles are right angles and the two adjacent sides are equal, so the other sides must also have to be equal, and so all the sides are equal, making it a square

Answer 2

The first thing we observe is that three of the four angles are right angles.
We have then that the possible quadrilateral is a rectangle or a square.
However, we also have two of its sides (not opposite) are equal, that is, RS = ST.
Therefore, the quadrilateral wanted is a square.
Answer:
The quadrilateral is a square.
