Question

show that line m is parallel to n
​

Answer 1

Step-by-step explanation:

In a parallel lines, the corresponding angles , alternate angle , interior alternate angle and exterior alternate angle are equal .

Here ,

<2 = <6 according to the corresponding angle.

<3 = <7 according to the corresponding angle .

<2 = <8 according to the exterior alternate angle .

<1 = <7 according to the exterior alternate angle.

<2 = <4 according to the alternate angle

<4 = <6 according to the alternate angle .

<6 = <8 according to the later are angle.

<1 = <3 according to the alternate angle

<3 = <5 according to the alternate angle

<5 = <7 according to the alternate angle .

<1 = <5 according to the corresponding angle .

<4 = <8 according to the corresponding angle .

hence , the line m and n are parallel to each other.

Answer 2

Answer:

2=6(corresponding angles)

1=5(............"...........)

3=7(............."........)

4=8(............".........)

1=3,2=4,5=7,6=8(V.O.A)

3=5,4=6(alternate angles)

These angles are only formed when when the two parallel lines are cut by a transversal
