Answer:
a. vertical
b. corresponding
c. same-side interior angles
d. alternate exterior
e.alternate interior
f. same-side exterior
g. vertical angles
h. corresponding angles
Step-by-step explanation:
Definitions: Alternate interior angles: two nonadjacent interior angles on opposite sides of the transversal.
Same-side interior angles: two interior angles on the same side of the transversal.
Corresponding angles: two angles in corresponding positions relative to the two lines
a. Angle 1 and Angle 4: These angles are vertical angles.
b. Angle 2 & Angle 6: These angles are corresponding angles.
c. Angle 3 and Angle 5: Same-side interior angles
d. Angle 1 & Angle 8: Alternate exterior
e. Angle 4 and Angle 5: Alternate interior angles
f. <2 & <8
Same-side exterior angles
g. <6 & <7 vertical angles
h. <3 & <7
Corresponding angles
