Find the Measure of the EXTERIOR ANGLE | Triangle Exterior Angle Theorem | Geometry

Here is a video tutorial on how to find the measure of the exterior angle of a triangle. We will go through 5 different examples together, where each problem gets a little bit harder. You will learn how to apply the Exterior Angle Theorem for a triangle, either to find the exterior angle itself or the value of x.

It only took 4 minutes to solve 3 questions that just took me 1 hour to figure out and failed. This video just saved another hour of struggle. Big like to this vid.

Dear mam,
In Problem 4 we could just--
Add X° (20) with 90°=110°

This is a great example of people are working with nothing but positive numbers. Is there a video that works with subtraction and negative

Im stuck in one that says -in a triangle with a tail - the exterior is (3x+6) and the interiors are 24 and (2x+18)
Thank u, from Egypt
