Step-by-step explanation:
let the Angles of //gm are
a , b , c and d respectively
we know that sum of adjacent angles of a //gm are added up to 180.
And opposite angles are equal
I,e a+b=180. Equation 01
c+d=180. Equation 02
a=c Equation 03
And
b=d. Equation 04
According to the given question
either a= b or c= d
let's take a = b
From equation 01
a+a=180
2a=180
a=90 , b = 90 (becoz a =b)
From Equation 03 and 4th
c = 90 And d=90
therefore angles of //gm are
a = 90 , b=90 , c=90 And d=90.
