ચોરસ $ABCD$ નાં ત્રણ શિરોબિંદુઓ $A (5, 3), B-2, 3)$ અને $D (5, 74)$ છે. આલેખપત્ર પર આ બિંદુઓનું નિરૂપણ કરો અને બિંદુ $ C$ ના યામ શોધો.
Option A
Option B
Option C
Option D
Solution

Plot the points $A(5,3), B(-2,3)$ and $D(5,-4) .$ Join $A B$ and $A D .$ As $A B C D$ is a square, so all its sides are equal and each angle is of $90^{\circ}$ measure. Therefore, the abscissa of the vertex $C$ will be $-2$ and ordinate $-4 .$ Hence, the coordinates of the vertex $C$ are $(-2,-4).$
