Q. The following steps are involved in construction of the incircle for the triangle $X Y Z$ in which $\angle Y=90^{\circ}$, $X Z=6 cm$ and $Y Z=4 cm$. Arrange them in sequential order from the first to the last. (A) Mark the foot of the perpendicular from $I$ onto $Y Z$ as $D$. (B) Construct the triangle $X Y Z$ with $\angle Y=90^{\circ}, X Z=$ $6 cm$ and $Y Z=4 cm$. (C) Draw a circle with $I$ as the centre and $I D$ as radius. This is the required incircle. (D) Draw the bisectors of $\angle X, \angle Y$ and $\angle Z$ and mark their point of concurrence as $I$.
