1. Since, two right triangles make a rectangle where O is equidistant point from A, B, C and D because O is the mid-point of the two diagonals of a rectangle. Since AC and BD are equal diagonals and intersect at mid-point. So, O is the equidistant from A, B, C and D. Class 8 Maths Chapter 3 Exercise 3.Read more
