Answer:
(1,8)
Explanation:
Given :-
- The three points of rectangle are given on graph .
And we need to find the fourth coordinate . We know that , in a rectangle
- Opposite sides are equal .
So , that , here the coordinates are ,
We can calculte the distance between them by subtracting the y coordinates as the X coordinates are same .
The distance between them is ,
Distance = (8 - 5 ) units
Distance = 3 units
- Hence the Fourth coordinate will be 3 units above (1,5) , as ,
Fourth coordinate = ( 1 , 8)
Hence the fourth coordinate is (1,8).
