Question3. QUILTING In the quilt design, assume that angles and segments that appear to be congruent are congruent. Indicate which triangles are congruent.
4. The vertices of $\triangle S U V$ and $\triangle S^{\prime} U^{\prime} V^{\prime}$ are $S(0,4), U(0,0)$, $V(2,2), S^{\prime}(0,-4), U^{\prime}(0,0)$, and $V^{\prime}(-2,-2)$. Verify that the triangles are congruent and then name the congruence transformation.
5. The vertices of $\triangle Q R T$ and $\triangle Q^{\prime} R^{\prime} T^{\prime}$ are $Q(-4,3), Q^{\prime}(4,3), R(-4,-2)$, $R^{\prime}(4,-2), T(-1,-2)$, and $T^{\prime}(1,-2)$. Verify that $\triangle Q R T \cong \triangle Q^{\prime} R^{\prime} T^{\prime}$. Then name the congruence transformation.
