QUESTION 5:-In a classroom, 4 friends are seated at the points A(3,4), B(6,7), C(9,4) and D(6,1). Champa and Chameli walk into the classroom after observing for a few minutes Champa asks Chameli, 'Don’t you think ABCD is a square?' Chameli disagrees. Using distance formula, find which of them is correct. : QUESTION 5:- In a classroom, 4 friends are seated at the points A(3,4), B(6,7), C(9,4) and D(6,1).
