Question
in the diagram below, \\( \triangle efg \cong \triangle opq \\), complete #2 - 7.
- \\( \overline { e f } \cong \\)
- \\( \angle p \cong \\)
- \\( \angle g \cong \\)
- \\( m \angle o = \\)
- \\( q o = \\)
- \\( \triangle g f e \cong \\)
Step1: Use the property of congruent triangles
When \(\triangle EFG\cong\triangle OPQ\), corresponding parts are congruent.
For \(\overline{EF}\), its corresponding side in \(\triangle OPQ\) is \(\overline{OP}\). So \(\overline{EF}\cong\overline{OP}\).
Step2: For \(\angle P\)
\(\angle P\) corresponds to \(\angle F\) in \(\triangle EFG\). So \(\angle P\cong\angle F\).
Step3: For \(\angle G\)
\(\angle G\) corresponds to \(\angle Q\) in \(\triangle OPQ\). So \(\angle G\cong\angle Q\).
Step4: For \(m\angle O\)
\(\angle O\) corresponds to \(\angle E\) in \(\triangle EFG\). Since \(m\angle E = 110^{\circ}\), then \(m\angle O=110^{\circ}\).
Step5: For \(QO\)
\(QO\) corresponds to \(GE\) in \(\triangle EFG\). Given \(GE = 7\mathrm{km}\), so \(QO = 7\mathrm{km}\).
Step6: For \(\triangle GFE\)
\(\triangle GFE\) corresponds to \(\triangle QOP\) (by re - arranging the order of vertices according to congruence). So \(\triangle GFE\cong\triangle QOP\).
