Question

a triangle has angle measurements of 66°, 80°, and 34°. what kind of triangle is it?
equilateral
isosceles but not equilateral
scalene

Explanation:

Step1: Recall triangle types

Equilateral: all angles \(60^\circ\). Isosceles: at least two angles equal. Scalene: all angles different.

Step2: Analyze given angles

Angles: \(66^\circ\), \(80^\circ\), \(34^\circ\). All are distinct (no two equal, none \(60^\circ\)).

Answer:

scalene (the option labeled "scalene")
