(a) Write down the coordinates of the point \(B\). (1)
(b) Write down the mathematical name of triangle \(ABC\). (1)
The coordinates of point \(D\) are \((1, -4)\)
(c) On the grid, mark with a cross (×) the position of \(D\).
Label the point \(D\). (1)
Label the point \(D\). (1)
(d) Find the coordinates of the midpoint of \(AB\). (2)
