(a)[2]
Describe completely the single transformation that carries triangle $A$ to triangle $B$.
(b)[2]
Triangle $A$ is transformed to triangle $C$ by a $90^\circ$ anticlockwise rotation about the origin $(0,0)$. Draw triangle $C$.
(c)[2]
Triangle $A$ is transformed into triangle $D$ by an enlargement with scale factor $3$, centre $(5,-5)$. Draw triangle $D$.
