Which angle measures would make a triangle with three equal side lengths

60

Step-by-step explanation:

If each side length must be identical, the same must be true for angles. If all the angles added are 180, divide 180 by 3 to get 60.

Answer: 60°

Step-by-step explanation:

By definition, an equilateral triangle is that triangle whose sides have equal lengths and its angles are equal.

Each angle of an equilateral triangle measures 60 degrees.

Therefore, the angle measure that would make a triangle with three equal side lengths is: 60°.
