what is the 3 attributes in a isosceles triangle?

Answer 1

The unequal side of an isosceles triangle is usually referred to as the 'base' of the triangle.
The base angles of an isosceles triangle are always equal.
When the 3rd angle is a right angle, it is called a "right isosceles triangle".
I don't know if this is the right answer or not.

Answer 2

* AT LEAST 2 sides are equal length (can be all three)

* AT LEAST 2 interior angles are same measure (can be all three)

* An equilateral triangle is actually also an isosceles triangle, but not all isosceles triangles are equilateral triangles.

Answer 3

2 sides
2 angles
