Question

prove that the bisectors of two adjacent supplementary angles include a right angle.​

Answer 1

Answer:

90°

Step-by-step explanation:

prove that the bisectors of two adjacent supplementary angles include a right angle.​

Let say two adjacent Supplementary angles are x & y

=> x + y = 180°

Bisector of x  = x/2

Bisector of y = y/2

(x/2) + (y/2)  =  (x + y)/2 = 180/2 =  90°

Hence it includes a right angle
