Question

if a ray stands on a line prove that the sum of the angle bisectors of the adjacent angles so formed is 90°

Answer 1

hey here is your answer
________________________________

On a straight line a ray standing on it will make two angles that are supplementary.

If one angle is x the other angle will be (180 -x). When you bisect the adjacent angles the sum will be

[x+(180-x)]/2

= [x+180-x]/2

= 180/2 = 90degrees

I hope it will help you.. ,

Answer 2

On a straight line a ray standing on it will make two angles that are supplementary .
If one angle is x the other angle will be (180-x) . When we bisect the adjacent angle , the sum will be
= [x+(180-x)]/2
= [x+180-x]/2
= 180/2=90 degrees .
