In triangles \( \triangle MNO \) and \( \triangle RTS \), we have the following angle measures:
For \( \triangle MNO \):
- \( m∠M = 78° \)
- \( m∠N = 34° \)
- \( m∠O = 68° \)
For \( \triangle RTS \):
- \( m∠R = 78° \)
- \( m∠S = 68° \)
- \( m∠T = 34° \)
Now, let's match the corresponding angles:
- \( m∠M \) (78°) corresponds to \( m∠R \) (78°), so \( ∠M ≅ ∠R \).
- \( m∠N \) (34°) corresponds to \( m∠T \) (34°), so \( ∠N ≅ ∠T \).
- \( m∠O \) (68°) corresponds to \( m∠S \) (68°), so \( ∠O ≅ ∠S \).
Therefore, the pairs of congruent corresponding angles in the two triangles are:
\( ∠M ≅ ∠R \), \( ∠N ≅ ∠T \), \( ∠O ≅ ∠S \).
So, the correct response is:
∠M≅∠R, ∠N≅∠T, ∠O≅∠S.
