Answer 8

why is an equilateral triangle considered isosceles

Answer 9

Going back to the posted definition:

An isosceles triangle can be defined as a triangle with **at least two** congruent sides.

An equilateral triangle has three congruent sides. Three is "at least two" so an equilateral triangle is also isosceles.

The problem in understanding stems from being taught earlier that an isosceles triangle has two sides congruent and getting the idea that two means exactly two.

The proper definition of isosceles triangle is a triangle with AT LEAST two sides congruent.

An equilateral triangle fits that so it is isosceles.
