Question

if angles in linear pair are congruent then each angle is right angle?
​

Answer 1

Answer:

yes

Step-by-step explanation:

as congruent angles are equal in magnitude

therefore 1 angle=x

x+x=180(as linear pair)

x=90°

Answer 2

In a linear pair the sum of two angles is = 180 degree
If the pair is congruent i.e. equal then
x + x = 180 ( both are equal )
2x = 180
x = 180 / 2
x = 90 degree
i.e. right angles ( hence proved )
