Question

If angle a and b are angles in a linear pair , and angle a and angle b are corresponding angles of two parallel lines ,then angle b+ angle d= what

Answer 1

Answer:

we know that sum of angles in a linear pair is 180 degree

a+b=180 ........equation(1)

and angle a = angle d ......( a and b are corresponding angles)

now , putting a=d in equation (1) , and we get

d+b=180

d=180-b
