Answer:
f) Same-side exterior angles
g) Vertical angles
h) None
i) Corresponding angles
j) Same-side interior angles
Explanation:
Part f
- ∠1 and ∠6 are same-side exterior angles.
Same-side exterior angles
When two lines are intersected by a transversal, the angles that are exterior to the two lines and on the same side of the transversal line are called "same-side exterior angles".
Part g
- ∠2 and ∠3 are vertical angles.
Vertical angles
When two straight lines intersect, two pairs of opposite vertical angles are formed.
Part h
Part i
- ∠2 and ∠10 are corresponding angles.
Corresponding angles
When two lines are intersected by a transversal, the angles that are in the same relative position are called "corresponding angles".
Part j
- ∠7 and ∠13 are same-side interior angles.
Same-side interior angles
When two lines are intersected by a transversal, the angles that are interior to the two lines and on the same side of the transversal line are called "same-side interior angles".
