No. The sum of the two opposite interior angles.
In any triangle exterior angle plus interior angles = 180 degrees
A isosceles right angle triangle will have 2 equal interior angles of 45 degrees and 1 angle of 90 degrees with its largest exterior angle being 180 -45 = 135 degrees.
...a right triangle.
The exterior angles of a regular n-gon measure 360/n degrees each and each interior angle is supplementary to its corresponding exterior angle. Thus each exterior angle measures 360/17 degrees which is approximately equal to 21.176 degrees. Each interior angle will then measure 180 - 360/17 degrees which is approximately equal to 158.824 degrees.
Yes, because it is equal to the sum of the two of them.
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
never
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
In any triangle exterior angle plus interior angles = 180 degrees
Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

No. The sum of the other two interior angles.
The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. To find the exterior angle, extend one side of the triangle and measure the angle formed outside the triangle. You can then calculate this angle by adding the measures of the two opposite interior angles. This theorem is useful in solving problems involving triangle geometry and angle relationships.
To find the measure of an exterior angle of a triangle, you can use the property that the exterior angle is equal to the sum of the two opposite interior angles. First, identify the exterior angle you want to measure, and then add the measures of the two non-adjacent interior angles. Alternatively, if you know the measure of one interior angle, you can subtract it from 180 degrees to find the exterior angle at that vertex.
To find the exterior angle of a triangle, first identify the two adjacent interior angles that form the exterior angle. The measure of the exterior angle is equal to the sum of these two interior angles. Alternatively, you can use the property that each exterior angle is equal to 180 degrees minus the adjacent interior angle. This relationship holds for all triangles.
two opposite interior angles.
Interior angle+exterior angle = 180 degrees
In triangle ADE, if angle GEA is an exterior angle, the remote interior angles are angles DAE and DEA. These are the angles inside the triangle that are not adjacent to the exterior angle GEA. According to the Exterior Angle Theorem, the measure of angle GEA is equal to the sum of the measures of angles DAE and DEA.
