Question

1. In the fig 1, 2 check two lines are parallel​

Answer 1

figure 1 ==>

we can state that the two lines are parallel by checking whether the adjacent angles are summing up to 180 degree

is 132 degree + 48 degree equal to 180 degree

132 degree + 48 degree = 180 degree

therefore, we can state that the two lines are parallel to each other.

figure 2 ==>

we can state that the two lines are parallel by checking whether the adjacent angles are summing up to 180 degree

is 106 degree + 73 degree equal to 180 degree

106 degree + 73 degree = 179 degree

therefore, we can state that the two lines are not parallel to each other.

Answer 2

Answer:

Step-by-step explanation:

fig 1

let the angle next to 132 be x

in parralel lines alternative interior angles are equal

so x = 48 if lines are parralel

we know that 132+x=180

x=180-132

x=48

alternative interior angles are equal hence lines in fig 1 are parralel

fig 2

let the angle next to 73 be x

in parralel lines alternative interior angles are equal

so x = 108 if lines are parralel

we know that 108+x=180

x=180-108=72

alternative interior angles are not equal

so lines are not parralel
