Chapter 14.2A, Problem 7A

a. Reflect triangle $ABC$ across line $j$, then across line $k$. Lines $j$ and k form a $60°$ angle, as shown. Describe the single transformation that takes triangle $ABC$ to triangle $A^{″}{B}^{″}{C}^{″}$

b. Reflect triangle $ABC$ across line $j$, then across line $k$. Lines $j$ and $k$ form a $45°$ angle, as shown. Describe the single transformation that takes triangle $ABC$ to triangle $A^{″}{B}^{″}{C}^{″}$.
