what sre quadrinal angles?How to find them?Is it related to trigonimetry?

Dear Student,

Quadrilateral has four sides, so with this four sides four angles can be formed internally. If ABCD is a quadrilateral, then four angles will be A, B C and D.
Finding these angles, it depends upon the givien information. But you must remember that for any quadrilateral, Sum of the interier angles A + B + C + D = 360^o

And yes, Sthese can be easily related to trigonometry because quadrilateral can be easily divided into two triangles.

Thanks.
