In \triangle EFG,△EFG, \overline{GE}\cong \overline{FG} GE ≅ FG and \text{m}\angle F = 55^{\circ}.M∠F=55 Find \text{m}\angle E.M
lidiya [134]

Answer: \text{m}\angle E=55^{\circ}.

Explanation:

We are given that,

In △EFG,

\overline{GE}\cong \overline{FG}

\text{m}\angle F = 55^{\circ}

To find: \text{m}\angle E

As we know that, angles opposite to the congruent sides of a triangle are congruent.

Thus, In △EFG

if \overline{GE}\cong \overline{FG} and \text{m}\angle F = 55^{\circ}

then it implies \text{m}\angle F =\text{m}\angle E= 55^{\circ}

Hence, we get \text{m}\angle E=55^{\circ}.
