Answer:
Vertical angles : Opposite angles made by two intersecting lines.
Corresponding angles : which occupy the same relative position at each intersection where a straight line crosses two others.
Alternate interior angles : when a transversal passes through two line then the angles that are formed on opposite sides of the transversal and inside the two lines.
Alternate exterior angles : angles on the outer side of each of those two lines but on opposite sides of the transversal.
Here, line k passes through the lines p and q,
Thus, by the above explanation,
Vertical pairs are, angle 1 and angle 4, angle 2 and 3, angle 5 and angle 8, angle 6 and 7,
Corresponding pairs,
angle 2 and angle 6, angle 1 and angle 5, angle 4 and angle 8, angle 3 and angle 7,
Alternate interior angles pair,
angle 4 and angle 5, angle 6 and angle 3,
Alternate exterior angles pair,
angle 2 and angle 8, angle 1 and angle 7,
Vertical angles are always equal in measure,
Now, the p and q are parallel lines,
So, the corresponding angles will be congruent as well as alternative interior or exterior will be congruent.
Therefore, the required pair,
Corresponding pairs :
m∠1=m∠5
m∠2=m∠6
Alternative interior pairs :
m∠3=m∠6
m∠4=m∠5,
Alternate exterior pairs :
m∠1=m∠8
m∠2=m∠7
Vertical pairs :
m∠1=m∠4
m∠5=m∠8
m∠2=m∠3
m∠6=m∠7
