Answer 2

Given :  parallel lines  co-interior angles  are

To Find :  correct option

(a) Complementary

(b) supplementary

(c) equal

(d) right angles​

Solution:

Transversal line : A line which passes through two lines in the same plane at two distinct points.

Corresponding  angles : A pair of angles that occupy the same relative position at each intersection by a transversal line  

Co- Interior angles : A pair of angles that are on the same side of the transversal and inside the given lines

Interior alternate angles : A pair of angles on the inner side of each of those two lines but on opposite sides of the transversal  

Exterior alternate angles : A pair of angles on the outer side of each of  those two lines but on opposite sides of the transversal  

Properties of angles formed by transversal line  with two parallel lines :

• Corresponding angles are congruent. ( Equal in Measure)

• Alternate angles are congruent.  ( Interiors & Exterior  both )  

• Co-Interior angles are supplementary. ( adds up to 180°)

Hence Correct option is  In case of parallel lines, co-interior angles are:  (b) supplementary
