Question

ABCD is a quadrilateralin which all the four angles are equal. show that AB||CD and AD||BC​

Answer 1

Answer:

if all the angles are equal then

Step-by-step explanation:

we know that in parllelogram oposites angles forms 180

I am representing angles as a b c and d

a+b =180

2a=180

a= 90

because a=b=c=d

similarly 2b=180

b=90

a+b=180

hence the apoosities angles form 180 then it is AB||cd
