Question

in a classroom 4 friends are seated at the point A,B,C and D as shown in Fig .7.8. champa and chameli walk into the class and after observing for a few minutes champa asks chameli , " Don'the you think ABCD is a square ?" chameli disagrees . using distance formula , find which of them is correct

Answer 1

Answer:

Please send with diagram

Answer 2

From figure, the coordinates of points A, B, C and D are (3, 4), (6, 7), (9, 4) and (6,1).

Find distance between points using distance formula, we get

AB = BC = CD = DA = 3√2

All sides are of equal length. Therefore, ABCD is a square and hence, Champa was correct
