Chapter 13.2, Problem 18MC

To determine

a.

To draw:

The triangle $\Delta ABC$ and three lines m, n, and p that intersect in a single point and reflect $\Delta ABC$ in line m to obtain its image $\Delta A^{\prime }{B}^{\prime }{C}^{\prime }$. Then reflect $\Delta A^{\prime }{B}^{\prime }{C}^{\prime }$ in line n to obtain $\Delta A^{″}{B}^{″}{C}^{″}$. Finally, reflect $\Delta A^{″}{B}^{″}{C}^{″}$ in line p to obtain the final image $\Delta A^{″}{B}^{″}{C}^{″}$ by using Geogebra.

To determine

b.

To find:

A single line q that could be used to reflect the original $\Delta ABC$ onto the final image.
