Given: A(1,0),B(4,0) and C(4,4).
To find: Coordinates of the point D such that ABCD is a rectangle.
Solution:
- Now, we have given three coordinates, So first we need to find the mid point of AC to find the point D. Let the point D be (x,y) and the centre of diagonal be O.
- So using mid point formula: (x1 + x2/2, y1 + y2/2)
O = ( (4+1) / 2, (4+0) / 2 )
O = ( 5/2 , 2 )
- Similarly, using mid point, we can find D:
( 5/2 , 2 ) = ( 4+x / 2, y+0 /2 )
- Equating the coordinates, we get:
4+x / 2 = 5/2, y+0 / 2 = 2
- Now solving for x and y, we get:
4+x = 5, y = 4
x = 1, y = 4
Answer:
The coordinates of the point D such that ABCD is a rectangle is x = 1, y = 4.
