Question

in the diagram below, \\( \triangle efg \cong \triangle opq \\), complete #2 - 7.

  1. \\( \overline { e f } \cong \\)
  2. \\( \angle p \cong \\)
  3. \\( \angle g \cong \\)
  4. \\( m \angle o = \\)
  5. \\( q o = \\)
  6. \\( \triangle g f e \cong \\)

Explanation:

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 \(\triangle GFE\cong\triangle QOP\).

Answer:

  1. \(\overline{OP}\)
  2. \(\angle F\)
  3. \(\angle Q\)
  4. \(110^{\circ}\)
  5. \(7\mathrm{km}\)
  6. \(\triangle QOP\)
