Answer 2

Answer:

option C is correct

Step-by-step explanation:

let two right angles x and y and add them:

angle x = 90 degree

angle y = 90 degree

on adding angle x and y ; we get :

angle x and y = 180 degree

90 degree + 90 degree = 180 degree

180 degree = 180 degree

Now, the sum of the measure of two right angles is 180 degree and to form a linear pair sum of measure of angle must be equal to 180 degree .

Hence,we can say that two right angles can form a linear pair.
