How many different triangles can be constructed with three sides, each measuring 5 centimeters?

1) one

2) more than one

3) none

The first thing we will do is define an equilateral triangle:

In geometry, an equilateral triangle is a regular polygon with three equal sides. In traditional Euclidean geometry, equilateral triangles are also equiangular, that is, the three internal angles are also congruent to each other, each angle with a value of 60 °

Every equilateral triangle consists of three equal sides and three congruent angles.

Therefore, there can be a triangle with three equal sides (5 centimeters in this case).

Answer:

1) one
