Find the coordinates of points $A, B, C, D$ in Figure.
Answer
Draw perpendiculars $AP, BP, CQ$ and $DR$ from $A, B, C$ and $D$ on the $x-$axis. Also, draw perpendiculars $AW, BX, CY$ and $DZ$ on the y-axis.
From the figure,
we have:
$AW = 1$ unit and $AP= 1$ unit.
So, the coordinates of vertex $A$ are $(1, 1).$
Similarly, $BX=1$ unit and $BP= 4$ units
So, the coordinates of vertex $B$ are $(1, 4).$
$CY = 4$ units and $CQ= 6 $ units
So, the coordinates of vertex B are $(4, 6)$.
$DZ = 5$ units and $DR= 3$ units
So, the coordinates of vertex $B$ are $(5, 3).$
