How To Find Exterior Angles Of A Triangle Jan 18 2024 0183 32 An exterior angle of a triangle is equal to the sum of the opposite interior angles Every triangle has six exterior angles two at each vertex are equal in measure The exterior angles taken one at each vertex always sum up to 360 176 360 degree 360 176 An exterior angle is supplementary to its adjacent triangle interior angle
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non adjacent interior angles Non adjacent interior angles may also be referred to as remote interior angles FACTS An exterior is equal to the addition of the two angles not right next to it 140 186 60 186 80 186 120 186 80 186 40 186 100 186 60 186 40 186 Problem 1 Find the value of x in the triangle shown below x 56 x 37

If the side of a triangle is extended the angle formed outside the triangle is the exterior angle g is the interior angle h is the exterior angle g h When any side of a triangle is extended the angle that is formed with this side and its adjacent side is called the exterior angle of a triangle There are three exterior angles in a triangle It should be noted that each exterior angle forms a linear pair with its corresponding interior angle
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
