Based on the Triangle Angle Sum Theorem, the sum of the angles inside a triangle must equal 180°. Which set of angles could form a triangle?(1 point)

1. 60°, 70°, 80°
2. 90°, 90°, 90°
3. 100°, 40°, 40°
4. 120°, 30°, 45°
Reponse 1 (60°, 70°, 80°) could form a triangle because the sum of these angles equals 210°, which is greater than 180°.
