How do you construct an exterior angle of a triangle where the sum of 2 of the interior angles is equal to an exterior angle?

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

Does exterior angle of a triangle equals the sum of the interior angles?
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.
How can you construct a 120 degree angle without using a protractor?
Construct an equilateral triangle which will have 3 equal interior angles of 60 degrees and 3 equal exterior angles of 120 degrees
What is relationship between exterior angles and opposite interior angles of a triangle?
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.
The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
What is the relationship between exterior and opposite interior angles?
In a triangle, each exterior angle is equal to the sum of the two opposite interior angles.
Which polygon has the larger exterior angle triangle or heptagon?
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
Does exterior angle of a triangle equals the sum of the interior angles?

What is the relationship between exterior and opposite interior angles?
In a triangle, each exterior angle is equal to the sum of the two opposite interior angles.
Which regular polygon's interior angles are half that of its exterior angles?
An equilateral triangle.
The angles of a triangle that are not adjacent to a given exterior angle?
Remote interior angles
How many remote interior angles are there for each exterior angle in a triangle?
