Question

The sum of angles of a quadrilateral ABCD is equal to 360°.
find the algebra expression
​

Answer 1

the algebraic expression can be :

if the angles are a,B,c and d then,

the required expression = a+b+c+d = 360°

Answer 2

Answer:

Let a quadrilateral ABCD which as angles ∠D , ∠A , ∠C and ∠B.

So, algebraic expression is  

∠D + ∠A + ∠C + ∠B = 360°.

This is the angle sum property of quadrilaterals.
