Find the values of \(x\) and \(y\) In \(\triangle J K L, \overline{J K} \cong \overline{K L}, m \angle J=2 x-y, m \angle K=2 x+2 y\) and \(m \angle L=x+2 y\)
Plot the given points on graph paper. Draw \(\triangle F A T\). Locate point \(C\) so that \(\triangle F A T \cong \triangle C A T\) $$F(1,2) \quad A(4,7) \quad T(4,2)$$
Write proofs in two-column form. Given: \(\overline{A D}\|\overline{M E} ; \overline{M D}\| \overline{B E}\) \(M\) is the midpoint of \(\overline{A B}\). Prove: \(\overline{M D} \cong \overline{B E}\)
Supply the missing reasons. Given: \(\overline{A B} \| \overline{D C} ; \overline{A B} \cong \overline{D C}\) Prove: \(\triangle A B C \cong \triangle C D A\) $$\begin{array}{l|l} \hline \text { Statements } & \text { Reasons } \\\ \hline 1 . \overline{A B} \cong \overline{D C} & 1\. ?\\\ 2 . \overline{A C} \cong \overline{A C} & 2\. ?\\\ 3 . \overline{A B} \| \overline{D C} & 3\. ?\\\ 4 . \angle B A C \cong \angle D C A & 4\. ?\\\ 5 . \Delta A B C \cong \Delta C D A & 5\. ?\\\ \hline \end{array}$$
Write proofs in two-column form. Given: \(M\) is the midpoint of \(\overline{A B}\); \(\overline{A D} \cong \overline{M E} ; \overline{A D} \| \overline{M E}\) Prove: \(\overline{M D} \| \overline{B E}\)
