Which statement proves that quadrilateral HIJK is a kite?

HI ⊥ IJ, and m∠H = m∠J

IH = IJ = 3 and JK = HK = SquareRoot 29, and IH ≠ JK and IJ ≠ HK

IK intersects HJ at the midpoint of HJ at (−1.5, 2.5)

The slope of HK = Negative two-fifths and the slope of JK = Negative five-halves

Answer is B
( I didn't see this on the site and figured I'd put it up)
