Question

the sum of two interior angle is equal to one exterior angle of triangle it is dash property ​

Answer 1

$\huge\bold\star\purple{Answer}$

Properties.

An exterior angle of a triangle is equal to the sum of the opposite interior angles. For more on this see Triangle external angle theorem. If the equivalent angle is taken at each vertex, the exterior angles always add to 360° In fact, this is true for any convex polygon, not just triangles......☺

Answer 2

Answer: exterior angle property

Step-by-step explanation:

The exterior angle theorem states that if a triangle’s side gets an extension, then the resultant exterior angle would be equal to the total of the two opposite interior angles of the triangle.
