Question

in parallelogram ABCD 4 angle a=5 angle c then find angle c​

Answer 1

Answer:

Let ABCD be a parallelogram in which ∠A=65  

∘

.

Since AD∥BC we can treat AB as a transversal. So,

∠A+∠B=180  

∘

 

65  

∘

+∠B=180  

∘

 

∠B=180  

∘

−65  

∘

 

∠B=115  

∘

 

Since the opposite angles of a parallelogram are equal, we have

∠C=∠A=65  

∘

 and ∠D=∠B=115  

∘

 

Hence, ∠B=115  

∘

,∠C=65  

∘

 and ∠D=115  

∘
