what is the angle sum property of a quadrilateral?please give me the answer as soon as possible.

 ITS 360^O

hmmm

jst like if given quadrilateral ABCD,

  angle A+ ang.B+ angleC + angleD = 360⁰

Thanks

360⁰

The answer is 360 degree

to find the angle's sum of a regular figure there is a formula

(n - 2) x 180

first of all you need to put value of 'n' as based on the sides of the figure.

then calculate to get the answer.

hope you understood!!!
