Answer:
Obtuse isosceles
Step-by-step explanation:
Two sides are the same length, so we know this is an isosceles triangle.
To determine if it's acute, right, or obtuse, we can compare it to a right triangle using Pythagorean Theorem:
c² = a² + b²
c² = 3² + 3²
c² = 18
c = √18
So if this were a right triangle, c would be √18, which is somewhere between 4 and 5.
Since the long side is greater than √18, we know this must be an obtuse triangle.
So this is an obtuse isosceles.
