Answer:
Coordinates of point H is (0,2).
Step-by-step explanation:
Given the co-ordinates of rhombus which are E (-2,3), F (0,4), G (2,3). We have to find the coordinate of point H.
let coordinate of point H are (a,b).
Now, as diagonals of rhombus bisect each other.
⇒ O is the mid-point of HF and EG.
Hence, by mid-point formula

⇒
, 
⇒
, 
⇒ (a,b)=(0,2)
Hence, coordinates of point H is (0,2).
