Corresponding angles have

- Different vertices
- Are on same side of transversal
- Have corresponding positions i.e. both upper left or lower left or upper right or lower right

So, corresponding angles are

- ∠ 1 and ∠ 5
- ∠ 2 and ∠ 6
- ∠ 3 and ∠ 7
- ∠ 4 and ∠ 8

For parallel lines,

corresponding angles are equal

Therefore,

∠1 = ∠5 ∠2 = ∠6

∠3 = ∠7 ∠4 = ∠8

To summarise,

Type | Angles |

Interior angles | ∠3, ∠4, ∠5, ∠6 |

Exterior angles | ∠1, ∠2, ∠7, ∠8 |

Pairs of Corresponding angles |
∠1 and ∠5, ∠2 and ∠6, ∠3 and ∠7, ∠4 and ∠8 |

Pairs of Alternate interior angles | ∠3 and ∠6, ∠4 and ∠5 |

Pairs of Alternate exterior angles | ∠1 and ∠8, ∠2 and ∠7 |

Pairs of interior angles on the same side of the transversal | ∠3 and ∠5, ∠4 and ∠6 |
