Exam questions on Transformations

1. Triangle $T$ has vertices $A(1,1)$, $B(4,1)$ and $C(4,3)$ on a coordinate grid.
   $T$ is reflected in the $x$-axis to give triangle $T_1$. Find the coordinates of the vertices of $T_1$.2 marks
2. The point $M(3,2)$ is plotted on a coordinate grid. The origin is $O$.
   $M$ is rotated $180^\circ$ about the point $(1,1)$. Find the coordinates of the image of $M$.2 marks
3. Triangle $A$ has vertices $(1,1)$, $(3,1)$ and $(3,2)$ on a coordinate grid.
   Triangle $B$ is the image of $A$ after an enlargement with scale factor $3$ and centre $(0,0)$. Find the coordinates of the vertices of $B$.3 marks
