Example<br />
Triangle B has vertices at (-2, 1), (-4, 1) and (-4, 4). T is a translation<br />
8<br />
represented by the vector , R is a reflection in the line y = -x and M is a<br />
3<br />
rotation of 90 0 about the origin. Find the vertices of MRT(B).<br />
Exercise<br />
Draw x- and y-axes with values from -8 to +8 and plot the point P(3, 2).<br />
R denotes 90 0 clockwise rotation about (0, 0);<br />
X denotes reflection in x = 0.<br />
H denotes 180 0 rotation about (0, 0);<br />
3 <br />
T denotes translation .<br />
