quadrilateral ghij is a square. what is m∠fhi? m∠fhi = ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​°

Explanation:

Step1: Recall property of square diagonals

The diagonals of a square are perpendicular to each other.

Step2: Determine angle measure

Since the diagonals of square $GHIJ$ intersect at $F$, $\angle FHI = 45^{\circ}$ because the diagonals of a square bisect the angles of the square.
