Recall the Triangle Angle Sum Theorem, which states that the sum of the interior angles of a triangle must be exactly \(180^\circ\).
For each set of angles, add the three angles together. For example, for the first set, calculate \(60^\circ + 70^\circ + 50^\circ\).
Check if the sum of the angles in each set equals \(180^\circ\). If the sum is exactly \(180^\circ\), then the angles can form a triangle.
Also ensure that each individual angle is greater than \(0^\circ\) because an angle of zero or less is not possible in a triangle.
Identify which set(s) satisfy these conditions and conclude that those sets of angles can form a triangle.
