Question

in the triangles, \\( \overline{bc} \cong \overline{de} \\) and \\( \overline{ac} \cong \overline{fe} \\). if \\( m\angle c \\) is greater than \\( m\angle e \\), then \\( \overline{ab} \\) is \\( \overline{df} \\).

Explanation:

Step1: Apply the Hinge Theorem

The Hinge Theorem states that if two sides of one triangle are congruent to two sides of another triangle, but the included angle of the first triangle is larger than the included angle of the second triangle, then the side opposite the larger angle is longer.
In \(\triangle ABC\) and \(\triangle FDE\), \(BC\cong DE\) and \(AC\cong FE\). The included angles are \(\angle C\) and \(\angle E\), and \(m\angle C>m\angle E\).

Step2: Compare \(AB\) and \(DF\)

By the Hinge Theorem, since \(m\angle C > m\angle E\) (the included angles for sides \(BC - AC\) in \(\triangle ABC\) and \(DE - FE\) in \(\triangle FDE\)), the side opposite \(\angle C\) (\(AB\)) and the side opposite \(\angle E\) (\(DF\)) have the relationship \(AB>DF\).

Answer:

longer than
