Interior angle+exterior angle = 180 degrees
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.
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
Yes, it is.
Such is called an exterior angle. A useful theorem is that an exterior angle is equal to the sum of its non adjacent interior angles.
An exterior angle of a triangle is defined to be the angle between one side of a triangle and the extension of an adjacent side. The measurement of this exterior angle is equal to the sum of the two opposite interior angles. See the related links for diagrams and sample problems.
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
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
any other exterior angle of the triangle * * * * * No. The sum of the two opposite interior angles.
The opposite exterior angle.
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.
