Question

what is sum of exterior angle of triangle​

Answer 1

Step-by-step explanation:

exterior angle of a triangle is equal to the sum of the opposite interior angles. If the equivalent angle is taken at each vertex, the exterior angles always add to 360 degrees.

Answer 2

Answer:

sum of exterior angles of a triangle = 360°

Step-by-step explanation:

Let the interior angles be x, y and z.

then, exterior angles are (180°-x), (180°-y) and (180°-z) respectively.

now, sum of exterior angles =180°-x+180°-y+180°-z

= 540° - (x+y+z)

= 540° - 180°

= 360°
