Question

Classify the triangle by its sides. The lengths of the sides are 9, 9, and 9.

equilateral


scalene


isosceles


obtuse

Answer 1

To find that a triangle can be made from these measurements you should know that the sum of two of its sides should be greater than the third side.

lets see if this rule applies...

9+9 = 18 ( greater that 9 ; its third side)

therefore, a triangle can be formed

as all of its sides are equal , it is an equilateral triangle

Answer 2

your answer would be equilateral
