A) (0, 0)
B) (4, 7)
C) (7, 4)
D) (7, 7)
E) (4, 4)
Correct Answer: D
Solution :
Let \[(\alpha ,\beta )\]be the co-ordinate of third vertex \[\therefore \] \[2=\frac{4-2+\alpha }{3}\] \[\Rightarrow \] \[\alpha =4\] and \[7=\frac{8+6+\beta }{3}\] \[\Rightarrow \] \[\beta =7\] \[\therefore \]Co-ordinate of third vertex is (7, 7).You need to login to perform this action.
