By using the diagram we can say that a and b is to filled with the reason that angles are vertically opposite angles and c is to be filled with the reason that when the lines are parallel the corresponding angles are congruent .
Given a figure in which there are eight angles.
We are required to fill the blanks with appropriate reason.
It is said that P and Q lines are parallel. Two lines are parallel if they do not meet in any condition.
a and b is to filled with the reason that angles are vertically opposite angles.
Vertical angles are basically formed when two lines meet each other at a point.
c is to be filled with the reason that when the lines are parallel the corresponding angles are congruent .
Hence by using the diagram we can say that a and b is to filled with the reason that angles are vertically opposite angles and c is to be filled with the reason that when the lines are parallel the corresponding angles are congruent .
