Answer 1

To find the pairs of congruent corresponding angles in triangles \( \triangle MNO \) and \( \triangle RTS \), we first list the angle measures given:

For \( \triangle MNO \):

• \( m\angle M = 78^\circ \)
• \( m\angle N = 34^\circ \)
• \( m\angle O = 68^\circ \)

For \( \triangle RTS \):

• \( m\angle R = 78^\circ \)
• \( m\angle S = 68^\circ \)
• \( m\angle T = 34^\circ \)

Now we can see the corresponding angles:

• \( \angle M \) in \( \triangle MNO \) corresponds to \( \angle R \) in \( \triangle RTS \) (both \( 78^\circ \)).
• \( \angle N \) in \( \triangle MNO \) corresponds to \( \angle T \) in \( \triangle RTS \) (both \( 34^\circ \)).
• \( \angle O \) in \( \triangle MNO \) corresponds to \( \angle S \) in \( \triangle RTS \) (both \( 68^\circ \)).

Thus, the pairs of congruent corresponding angles are:

• \( \angle M \cong \angle R \)
• \( \angle N \cong \angle T \)
• \( \angle O \cong \angle S \)

So, the correct response is: ∠M≅∠R, ∠N≅∠T, ∠O≅∠S (second option)
