Answer 2

Answer:

the angles which is vertically opposite to each other with same. degree

Step-by-step explanation:

• a transversal is passing through parallel line

•Take them as l and m and transversal as xy

as given in fig above

• now suppose as given in second figure

THEREFORE

By linear pair property ;

|_ 1 +|_2 = |_3 +|_4 ..........( 1)

AND

|_1+ |_3=|_4+|_2.........(2)

SO

equating (1)&(2)

|_1+|_2=|_2+|_4

|_1+|_3=|_2+|_1

|_1=|_4 and |_2=|_3

HENCE PROVED

THEREFORE , VERTICALLY OPPOSITE ANGLES ARE EQUAL
