Question

The sum of all exterrior angle of a triangle is is

Answer 1

Answer:

360°

Step-by-step explanation:

let X Y Z be the interior angles of a triangle,

therefore exterior angles sum will be,

(180-X)+(180-Y)+(180-Z),

= 540-(X+Y+Z),

= 540-180,

= 360°

Therefore,

sum of all exterior angles of a triangle is 360°.
