Question

Prove that the bisector of two adjacent supplementary angles are at right angles

Answer 1

Step-by-step explanation:

Let the adjacent angles be x&y.

Let the adjacent angles be x&y.Given x+y=180°

Let the adjacent angles be x&y.Given x+y=180°When bisector are drawn, the angle between the bisector is:

Let the adjacent angles be x&y.Given x+y=180°When bisector are drawn, the angle between the bisector is:x/2+y/2=x+y/2=180/2=90°
