Question

A transversal intersects two lines. If the measures of pair of
interior angles are 79° and 990
then two lines are

Answer 1

Step-by-step explanation:

interior angles are =79°

then two lines=990

990-79

911 this is correct answer

Answer 2

Concept:

When transversal line cut two parallel lines, the sum of two interior angles is 180°

Given:

Two interior angles=79° ,99°

Find:

The sum of two interior angles as well as what they depicts

Solution:

If two lines are parallel,transversal lines cut the two lines,then the sum of two interior angles is supplementary(180°)

Sum of two angles =79°+99°

                               =178°

This shows that the two lines cut by the transversal line is non parallel.

Hence,the two lines are non parallel
