Question

(d) Prove that the quadrilateral ABCD is a square if A =(4, 3), B = (6,4), C =(5, 6) and D =(3,5).​

Answer 1

Answer:

Yes it is a square

Step-by-step explanation:

First if we find the distance between points

AB= √5

BC=√5

CD=√5

AD=√5

But if all sides are equal it can be rhombus also. So we need to verify whether the diagonals are equal or not.

AC=√10

BD=√10

As diagonals are also equal Thus is a square.
