Chapter 14.2B, Problem 7A

To determine

a.

To describe:

The single transformation that takes triangle $ABC$ to triangle $A^{‴}{B}^{‴}{C}^{‴}$, by reflecting triangle $ABC$ across line $j$, then across line $k$, then across line l. Lines j, k, and l from $60°$ angles as shown in figure $1$.

To determine

b.

To describe:

The single transformation that takes triangle $ABC$ to triangle $A^{‴}{B}^{‴}{C}^{‴}$, by reflecting triangle $ABC$ across line $j$, then across line $k$, then across line l. Lines j, k, and l from $45°$ angles as shown in figure $3$.
