There are two windows in Elana's bedroom, each of which has four
right angles. => means both windows could be squares, or rectangles, or one of each kind
One of her windows has four congruent sides. => means this window is a square
The other window contains two pairs of opposite sides that are equal, but all four sides are not congruent. => means this window is a rectangle
since a square is a special kind of rectangle, your answer is:
3). Both windows are rectangles.
