Angles in matching corners are corresponding angles.
Corresponding angles:
<1 & <5 ; <2 &6 ; <3 & <7; <4 & <8
Vertical angles: Opposite angles are vertical, they share the same vertex.
<1 & <4 ; <2&3 ; <6 & 7; <5 & <8
Alternate exterior angles:
A pair of angles on the outer side of the parallel lines, but on opposite sides of the transversal.
<1 & <8 ; <2 & <7
Alternate interior angles:
A pair of angles in the inner side of the parallels, but on opposite sides of the transversal.
<3 & <6 ; <4 & <5
Consecutive interior angles:
Angles on one side of the transversal, and inside the 2 parallels.
<3 & <5 ; <4 & <6
Consecutive exterior angles: Angles that lie on the same side of the transversal outside the parallel lines:
<2 & <8 ; <1 & <7
