Question

given l//m,and L1= 80°, find the measures of all the order angles in the figure shown along side​

Answer 1

Step-by-step explanation:

angle 1 = 80

____________

angle 2 = 180-80(linear pair)

angle 2=100

____________

angle 3 = angle 1 (vertically opposite angles)

angle 3 = 80

_____________

angle 2=angle 4 ( vertically opposite angles)

angle 4= 100

_____________

angle 6=angle 1 (corresponding angles)

angle 6=80

_____________

angle 5=angle 4 (corresponding angles)

angle 5 = 100

______________

angle 7=angle 5( vertically opposite angles)

angle 7= 100

______________

angle 8=angle 6 (vertically opposite angles)

angle 8=80
