Answer:
a) alternate interior angles
b) vertical angles
c) corresponding angles
d) linear pair
Step-by-step explanation:
Alternate interior angles:
- formed when a transversal intersects two lines on the same plane
- located on the inside/interior side of the parallel lines, but they're on the opposite sides
- these angles are congruent
- Example: angles D and E
Vertical angles:
- pair of opposite angles formed by lines that intersect
- these angles are congruent
- Example: angles E and H
Corresponding angles:
- angles that have the same relative position, formed by a transversal intersecting two parallel lines
- these angles are congruent
- Example: angles A and E
Linear pair:
- pair of adjacent angles formed by two intersecting lines
- angles have measures that add up to 180 degrees
- Example: angles C and D
