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
No. The sum of the other two interior angles.
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.

two opposite interior angles.
Interior angle+exterior angle = 180 degrees
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
The opposite exterior angle.
No. It is equal to the sum of the opposite interior angles.
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.
