Question

Raoul saw a bridge like the one shown when he was on vacation.

∆ABC and ∆DEF are ≅ equilateral triangles. The length of side BC is 12 ft. What is the length of side EF?

Answer 1

The length of side EF is 12 ft.

Step-by-step explanation:

An equilateral triangle is a special type of triangle that has three equal sides and three equal angles. Each angle in an equilateral triangle measures 60 degrees. The term "equilateral" is derived from the Latin words "aequus," meaning equal, and "latus," meaning side.

In the given diagram, we have two equilateral triangles, ∆ABC and ∆DEF. The length of side BC is given as 12 ft. Since both triangles are equilateral, all sides are equal in length. Therefore, the length of side EF is also 12 ft.
