You have to extend the line opposite to the 2 angles
For example, if u have a triangle ABC, and if BC is the base, then
if u produce BC, the exterior angle formed will be equal to angle A + angle B
OR
if u produce CB then the exterior angle will be equal to angleA+ angle C
This is true about all the sides(not only the base side)
I just gave the base as an example
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
Construct an equilateral triangle which will have 3 equal interior angles of 60 degrees and 3 equal exterior angles of 120 degrees
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
They are all 60 degrees.
In a triangle, each exterior angle is equal to the sum of the two opposite interior angles.
Interior Angles of a Triangle: 60 Exterior Angles of a Triangle: 120 Interior Angles of a Heptagon 128 (approx) Exterior Angles of A Heptagon 52 (approx) Answer: Triangle
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
The interior angles of a triangle add up to 180 degrees. The exterior angles of a triangle add up to 360 degrees.

The sum of the interior angles of any triangle is 180 degrees.
The exterior sum of the angles of any polygon including a triangle is always 360 degrees.
They are all 60 degrees.
A triangle has 3 interior angles that add up to 180 degrees and 3 exterior angles that add up to 360 degrees
In a triangle, each exterior angle is equal to the sum of the two opposite interior angles.
An equilateral triangle.
